How has the F-series evolved over time? The progression from earlier models to the F55 Friction showcases Brine’s commitment to improving shaft design:
- Enhanced materials: Moving from basic aluminum to high-end Scandium alloys
- Improved durability: Addressing common issues like bending and breakage
- Weight reduction: Maintaining strength while decreasing overall shaft weight
- Grip innovation: Introducing the Dual Diamond texture on the F55 Friction
Unboxing the Brine F55 Friction: First Impressions
Upon first handling the F55 Friction, players will immediately notice its striking appearance. Available in various colors, including an eye-catching electric blue, the shaft makes a bold visual statement. While some players prefer understated designs, the F55 Friction finds a balance between flair and function.
Does the shaft’s appearance affect performance? While aesthetics don’t directly impact play, a confident player is often a better player. The F55 Friction’s sleek look may provide that extra boost of assurance on the field.
Revolutionary Grip Technology: The Dual Diamond Texture
The standout feature of the F55 Friction is undoubtedly its grip. Brine has developed a Dual Diamond texture that covers the shaft, providing a unique tactile experience for players.
Key Aspects of the Dual Diamond Grip:
- Subtle texture: Noticeable without being overpowering
- Balanced grip: Allows hand movement while maintaining control
- Candy-cane pattern: Mimics popular taping styles on the upper half
- No added weight: Texture is part of the shaft, not an additional layer
How does this grip compare to traditional taping methods? For many players, the F55 Friction eliminates the need for additional grip tape. The built-in texture provides a consistent feel along the entire shaft, potentially improving overall control and reducing maintenance time.
Weight and Durability: The Scandium Advantage
Brine’s use of a high-end Scandium alloy in the F55 Friction continues the brand’s tradition of creating lightweight yet durable shafts. This material choice offers several benefits to players:
- Excellent strength-to-weight ratio
- Resistance to dents and dings
- Long-term durability under high-intensity play
How does Scandium compare to other shaft materials? Scandium alloys often outperform standard aluminum in terms of strength while maintaining a similar weight. Compared to carbon fiber composites, Scandium offers better impact resistance and a more consistent feel throughout its lifespan.
Performance on the Field: Putting the F55 Friction to the Test
After extensive use in high-intensity indoor lacrosse sessions, the F55 Friction proves its worth as a top-tier shaft. Players may notice several performance benefits:
- Improved ball control due to the grip texture
- Consistent feel in various weather conditions
- Reduced hand fatigue during extended play
- Minimal signs of wear even after heavy use
Does the F55 Friction enhance shooting accuracy? While individual results may vary, the combination of lightweight design and improved grip can potentially lead to more precise shots and passes.
Value Proposition: Justifying the Premium Price Tag
With a retail price of $129.99, the F55 Friction positions itself in the premium shaft market. This price point may give some players pause, especially when considering the eventual replacement of gear.
Is the F55 Friction worth the investment? Consider the following factors:
- Long-term durability potentially reducing replacement frequency
- Elimination of grip tape expenses
- Performance benefits that may improve overall play
- Brand reputation and warranty support
For serious players looking to maximize their equipment’s performance, the F55 Friction’s benefits may outweigh its initial cost.
Comparing the F55 Friction to Competitor Shafts
To truly understand the F55 Friction’s place in the market, it’s essential to compare it to similar offerings from other brands. How does it stack up against the competition?
F55 Friction vs. Traditional Metal Shafts:
- Grip Technology: F55 Friction offers built-in texture, while most require taping
- Weight: Comparable to high-end aluminum shafts
- Durability: Often surpasses standard aluminum in impact resistance
F55 Friction vs. Composite Shafts:
- Feel: More consistent than composites, which can soften over time
- Temperature Sensitivity: Less affected by extreme weather conditions
- Repair: Metal shafts can often be bent back into shape, unlike composites
Are there any shafts that directly compete with the F55 Friction? While several brands offer premium metal shafts, few combine the specific grip technology and material composition of the F55 Friction, making it a unique option in the market.
Customization and Accessories: Enhancing the F55 Friction Experience
While the F55 Friction comes well-equipped out of the box, players may want to further personalize their setup. What options are available for customization?
- End Caps: Replacing the standard end cap can fine-tune weight distribution
- Grip Overlays: For players wanting additional grip in specific areas
- Shaft Wraps: Decorative options to change appearance without affecting grip
Does customizing the F55 Friction void its warranty? Players should consult Brine’s warranty terms before making significant modifications to ensure they maintain coverage.
Maintenance and Care: Preserving Your Investment
To maximize the lifespan and performance of the F55 Friction shaft, proper maintenance is crucial. What steps should players take to care for their shaft?
- Regular Cleaning: Wipe down with a damp cloth to remove dirt and sweat
- Inspection: Check for any developing cracks or dents after intense games
- Storage: Keep in a cool, dry place away from extreme temperatures
- Transport: Use a padded bag to prevent damage during travel
How often should the F55 Friction be replaced? With proper care, many players find premium shafts like the F55 Friction can last multiple seasons. However, replacement should be considered if significant damage occurs or performance noticeably declines.
Player Feedback: Real-World Experiences with the F55 Friction
While professional reviews provide valuable insights, hearing from everyday players offers a more diverse perspective on the F55 Friction’s performance. What do users say about their experiences?

Gear Review: F55 Friction Shaft by Brine Lacrosse
[rwp-review id=”1″]
Company: Brine Lacrosse / Product: F55 Friction Shaft / Price: $129.99
Brine’s venerable F-series shafts hold a special place in my heart. My very first handle, back in the stone age of 2001, was a Brine F10. In the first game of the playoffs in my senior year of high school, I learned my first lesson about aluminum and upgraded to a Brine F-15 shortly thereafter. The F15 has endured a decade of service and then some without breaking. During that time, I’ve broken composite shafts, shafts named after Japanese swords, and shafts that were supposedly unbreakable. But the F15 remains.
It came, then, as a delight when Krieg Shaw placed the Brine F55 Friction in my hands and told me to give it a whirl. After using it for a month or so, here’s what I’ve found.
Appearance… +7.5
I tend to gravitate towards shafts which are non-descript, plain, conservatively-designed, or otherwise visually unremarkable. The F55 is not that; but it’s not gaudy either. It’s got a sharp appearance and comes in a variety of colors.
The shaft I tested was electric blue. While I typically wouldn’t select that color of shaft, it quickly grew on me and after awhile I didn’t miss the sight of my silver Kryptolyte one little bit.
Grip… +10.0
If you’re paying any attention to the name (“Friction”), you might have supposed that there was something to the grip of the F55. You’d be right. Here’s Brine’s description of what they’ve cooked up here:
Now, I’ve tested a number of sticks with built-in grip. Usually, I’m not a huge fan, preferring instead to add my own grip with hockey tape. The F55 Friction, however, is different. The Dual Diamond texture is very mild; you know it’s there but it isn’t so grippy that it affects how your hands slide on the metal. Again, here’s how Brine describes their Diamond Grip:
Brine went to the trouble to candy-cane the Diamond Grip texture pattern on the top half of the handle to emulate a popular taping convention. I don’t usually tape my stick in that way, but in this case I liked it (probably because of how mellow the texture is).
Grip is a matter of personal preference. I use grip (usually tape) merely as a means of getting my bearings; I don’t rely on it to hold onto the stick. For me, the F55 Friction is perfect. If you’re looking for something more aggressive however, it might not do the trick.
Weight… +10.0 // Durability… +10.0
While the Friction might be new, the F55 has been Brine signature since the mid-2000s. Made of a high-end Scandium alloy, the F55 has always offered a premium balance of light weight and high strength. The F55 Friction is no different. Unlike other handles which use some variation of polymer coating, the Diamond Grip is not additive and therefore does not increase the weight. Meanwhile after several high-intensity indoor lax sessions, I’ve yet to find any significant dings or signs of wear along the shaft. Suffice it to say, I’m impressed.
Value… +5.0
I’m not one to drop a ton of money on a shaft. My seemingly-immmortal F15 aside, most sticks eventually break. My old Katana (which had a similar texture to the Friction) had a price tag of $120 and it snapped in two about a month after the warranty ran. The F55 Friction retails for $129.99 at Lacrosse.com. Maybe I’m cheap, but I’d have a hard time paying that much for a 30″ stick. $130 is just a little rich for my blood. That said, I do think that this is an outstanding piece of equipment and perhaps I’m just out to lunch on the cost of doing business.
Overall… 8.4/10
The F55 Friction looks good, feels great, and performs like a champ. The grip is perfect for players that don’t usually want any grip on their handles. I’m a bit concerned about the price, but I recommend dropping by your local lacrosse shop and putting one in your hands. You might just love it.

Super Duplex Valves | F53 and F55
Super Duplex A182 F53, A182 F55, A890 Gr. 5A and A890 Gr. 6A Valves
Looking for a valve in this exotic alloy? Find it in the following configurations: Ball, Butterfly, Cast, Check, Control, Cryogenic, Custom made, Foot, Forged, Gate, Globe, Needle, Plug, and Safety relief, as well as Strainers.
Due to their ability to resist corrosion, alloy valves made of super duplex are often quite useful in various industrial processes including seawater systems and desalination plants. These corrosion-resistant valves are extremely functional in marine conditions such as subsea, offshore, and platform work. Also, these severe service valves are perfect in the chemical industry, especially when dealing with a variety of corrosive agents such as the following:
- chlorides used in flue-gas cleaning
- steam
- fatty acids
- concentrate brine
- sea water
- pulp water
- potable water
- pulp liquors at 220°F (104°C)
- sulfuric acid (35-40% @ 185°F (85°C), plus 5% organics)
- sulfuric acid (15-30% @ 140-160°F (60-71°C))
Lastly, these high-alloy valves are advantageous when the Pitting Resistance Number (PREN) is required.
Super duplex, used in exotic alloy valves, is a common name for a wide range of materials. Made of a 50/50 mixed microstructure of austenitic and ferrite, super duplex stainless steel is much stronger than austenitic and ferritic steel grades that have similar corrosion resistant properties. This increased strength is caused by the augmented chrome and nickel content in their composition. The super duplex stainless steel used in exotic alloy valves ranges in type and grade dependent on the method the raw material was developed and dependent on the international standards and norms used.
A variety of normalization codes and references can be used to identify super duplex valves. Using American ASTM norms, if you are seeking a forged super duplex valve, you would ask for an A182 F53 or F55 valve; however, if you were seeking a cast super duplex valve, you would be looking for an A955 Gr. 5A or 6A valve or an A351 CD3MWCuN valve, previously known as an A890 Gr. 5A or 6A valve. According to German DIN norms, super duplex is recognized as 1.4501 and 1.4410.

90,000 Condensation – steam – propane
Condensation – steam – propane
Page 1
Condensation of propane vapor occurs due to its cooling in direct contact with cooling water. The final temperature difference between propane and water in the condenser and between propane and brine in the evaporator is 0 5 – 2 C.
[2]
Fig. 116 shows the dependence of the Wobbe number, heat of combustion, density and temperature of condensation of propane and butane vapors at an excess pressure of 1 05 kgf / cm2 on the content of propane and butane in a mixture with air.The combined graph allows you to trace the change in the properties of mixtures when the gas-air ratio changes and is an operational document when monitoring the operation of mixing devices. If necessary, graphs of this type are drawn up for various mixtures of propane and butane.
[4]
Product separation and purification system consists of steam-heated evaporators; the system maintains an increased pressure to enable condensation propane vapor with cooling water, followed by stripping the residual amount with water vapor at atmospheric pressure.[5]
From the bottom of the reboiler 3, hot gasoline, freed from dissolved propane, enters the refrigerator 8, and then, by means of the pump 9, is supplied in a cold state to the jet absorber for condensation of propane vapors .
[6]
For stripping propane from deasphalted solutions, conventional evaporators with a vapor space heated by steam are used. For cooling and condensation propane vapors , deasphalted materials and asphalt, air coolers of the AVG type are used.[7]
Ammonia compressors AV-22, AV-100, AU-200 have been used for pumping liquefied hydrocarbon gases at KBSG, GNS and GNP for many years. During the operation of these compressors, condensation of propane and butane vapors is observed on the cylinder walls, since the wall temperature is below the saturation temperature. In addition to vapor condensation, propane and butane are adsorbed (absorbed) by oil during compression and desorption (extracted) from oil during expansion.For this reason, the flow of the Compressors is significantly less than the volume described by the pistons.
[9]
The reflux to the ethylene column is condensed by the vaporization of the high pressure propane refrigerant. In a boiler operating at a temperature of – 7, heat is transferred due to condensation of circulating propane vapors , which significantly reduces the cost of compressing the main refrigerant.
[11]
The main factors of the deasphalting process are not only the temperature, pressure and ratio of propane to the feed, but also the type of solvent, as well as its purity.Butane is less selective than propane and even more so ethane. Methane and ethane make it difficult for the condensation of propane vapors in the condenser-refrigerator. With a significant concentration of ethane in the solvent, the deasphalting process would have to be carried out at excessive pressure; therefore, technical propane should contain no more than 7% (wt.) Of other hydrocarbons of the same series, including no more than 3% ethane. The presence of propylene and butylenes is also undesirable as they increase the solubility of resins and polycyclic aromatic hydrocarbons.In technical propane, there should be no sulfur-containing compounds, as they cause corrosion of apparatus and pipelines.
[12]
An increase or decrease in pressure in the distillation column is accompanied, as a rule, by a corresponding increase or decrease in the temperature regime. The preference of the second rectification option is obvious, since the increased pressure makes it possible to use water for condensation of propane vapors , and not special refrigerants and expensive low-temperature cooling systems.[13]
An increase or decrease in pressure in the rectification boiler is not accompanied, as a rule, by a corresponding increase or decrease in the temperature regime. So, to obtain propane as rectification, the required temperature of the top of the boiler at pressures of 0 1 and 18 MPa will be – 42 and – f 55 C, respectively. The preference of the second rectification option is obvious, since the increased pressure makes it possible to use water for condensation of propane vapors , not special refrigerants and expensive low-temperature cooling systems.Distillation, for example, under vacuum, allows for the selection without noticeable decomposition of oil fractions boiling away at temperatures ax exceeding the heating temperature of the raw material by more than 100-15 ° C.

pork – Tenderness of Cheesy Pork Chops
I had similar results with pork chops. I think part of the problem was the quality of the meat I used.A nicer cut of pork from a local farm was much better than something from Kroger (grocery store).
You can shorten the marinade time. You basically did 16 hours like you cooked too. I usually just brine for 1-2 hours in 7% salt 3% sugar brine and then skim this off before cooking.
How did you determine the cooking time? The amount of time you cook the Sous Vide for can change the texture in some nasty ways (especially for lobsters).Depending on how you cut your meat, you may have been able to take it out much earlier. If you don’t use it regularly, I highly recommend Douglas Baldwins: A Practical Guide to Sous Vide. I haven’t read his book, but the online resource is invaluable.
Based on the Baldwin charts, you will need to cook 1cm of pork chop for 1:21 minutes to get to the safe area. Thus, you cooked it 6 times longer than necessary. If I remember correctly, it is not recommended to leave lean meat for more than 2-4 hours longer than necessary, and you definitely exceeded that.
The advantage of sous vide is precise temperature control. There are two main ways to use this control. The first is to precisely and precisely reach the desired temperature through the piece of meat. This is ideal for tender, low-fat meats. In these cases, you should cook the meat for the minimum safe time, or take it for convenience, as advanced cooking will affect the texture of your dish. The second way is to use it for low and slow style cooking, allowing you to enjoy all the benefits of a long cooking time and a soft nature without having to cook the meat until well done.The second method is ideal for short ribs, roast, Boston butt. However, if you are cooking something like pork chops, the extra cooking time will not make the end result more tender and will ultimately have a negative effect.
Heat transfer coefficient. Heat transfer coefficient (table
Approximate values of heat transfer coefficients are given in table. 6.2, and the heat transfer coefficients – in table. 6.3. The average temperature difference in co-current or counter-current flow of heat carriers is equal to [c.147]
The main task of the thermal calculation of the heat exchanger is to establish the value of the total heat transfer coefficient / C, determined by equation (6.2). Since, when determining / C, the thermal resistances of contaminants r 1 are estimated roughly (see Table 7 of the Appendix), it is permissible to calculate the partial heat transfer coefficients a using simplified formulas. This approach greatly simplifies the methodology for engineering calculations of heat exchange equipment and facilitates the programming of problems if they are solved using a computer. [c.149]
The approximate limits of the values of the heat transfer coefficients are given in table. UI-18, and heat transfer coefficients – in table. UL-19. Heat transfer coefficients of heaters see [UI-32, UI-ZZ]. [c.607]
If liquids are artificially mixed, the heat transfer coefficient should be determined by the formulas corresponding to this case. To preliminary determine the heat transfer coefficient of some fluids, you can use table.6 and 7. 188 [c.188]
Coefficient K is determined by the coefficients of heat transfer (heat transfer), which characterize the efficiency of heat transfer from a hot agent to a cold one. When solving problems of calculating heat transfer in heat exchangers, the coefficient K is usually selected from practical data, taking into account the main factors on which it depends. Practical data on the heat transfer coefficients of some heat exchangers of high-performance installations are given in table.5. [c.102]
In the table. 4-5 show the approximate values of the heat transfer coefficients (rounded off) for water and air, calculated according to the above formulas for the main cases of convective heat transfer, and in table. 4 6 – approximate values of heat transfer coefficients obtained practically for various cases of heat transfer. [c.174]
As shown in the section Basic equations of the heat transfer process (see Ch. 3), in the general case, both the time constant and the self-leveling coefficient of volumetric reactors depend both on the heat exchange characteristics of the reactor (the method of heating or cooling , heat transfer coefficients, heat transfer and heat loss, heat exchange surface), and from the thermophysical properties (heat capacity) of the reaction mass (table.6). [c.102]
In-tube boiling evaporators are used mainly in freon refrigeration units, where their advantages (small amount of charged refrigerant) are especially noticeable. Due to the low heat transfer coefficients during the boiling of freons, the heat transfer coefficients in the evaporators are low, despite the large values of the heat transfer coefficients on the side of the coolant (Table VI-1). [c.141]
The total heat transfer coefficient when heating the reactor, given that heating is carried out by condensing water vapor, can be taken equal to the heat transfer coefficient of the stirred medium.To calculate this heat transfer coefficient, we take additional conditions, the reaction mass is mixed in a vessel with partitions, an open turbine stirrer with a diameter = 0 / 3.5 = 1400 / 3.5 = 400 mm at a peripheral speed w = 3 m / s (see Table 9.1 ). [c.258]
The algorithms are given in table. 11.3, where the numbers of the formulas used to set the initial approximations when performing iterative calculations are circled.To accelerate the convergence of iterative calculations, the Iteration block is used. The equipment vector of this simulating unit contains the following parameters of pressure drops in the pipe and annular space, module k, basic flow rates for calculating the heat transfer coefficient in the tube and annular spaces, coefficients a and P sign of the aggregate state of heat transfer fluids, heat transfer area [c.596]
App. heat transfer through a flat multilayer wall into equation (1) – see.tab. 1.4 – should include dt – heat transfer coefficient determined by equation (8), and A7 = p – mean logarithmic temperature difference between flows, calculated by equation (9). In dependence (8) the heat transfer coefficients for [c.31]
Having the values of the determining criteria according to the corresponding heat transfer equation (see Table V. 12), find the value of the heat transfer coefficient for the given heat carrier. Using the same scheme, we calculate the heat transfer coefficient for the coolant a2.We calculate the heat transfer coefficient [c.434]
As for heat transfer, then from expressions (3.4.4) and (3.4.6) it can be seen that the parameter that determines both the local and average heat transfer coefficient and hx (in the section from 0 to x), is the complex [- qp (0)] V2. This parameter is shown in table. 3.4.1, and the graph of its dependence on P g is shown at [c.81]
The adiabatic increase in pressure along the line 1-2 is performed for the liquid-phase state of the working substance, while the expended work of compression / in the pump turns out to be many times less work of expansion of the I vapor phase.Another positive property of the Rankine cycle is the conduct of heat transfer processes, in which the main amounts of heat are transferred (the heat of evaporation of water in the boiler tubes of the steam generator and the heat of condensation of the exhaust steam in the condenser) at high heat transfer coefficients (see Table 3.1), which makes it possible to reduce significant here heat transfer surfaces. [c.291]
Boiling of liquid on the surface of flooded horizontal pipes, in evaporators with natural convection heat can be conducted through pipes immersed in liquid and heated from the inside by condensing steam.For very small temperature differences, the heat transfer coefficients are of the same order of magnitude as when heating a liquid. However, with an increase in the temperature difference, the heat transfer coefficient increases significantly due to the high intensity of mixing during boiling. Boiling goes into a regime called bubble boiling. When the critical temperature difference is reached, the heat flux d P reaches its maximum value. With a further, even insignificant, increase in A / the heat flux sharply decreases due to the formation of a more or less continuous vapor film on the surface.If the temperature differences are very significant (which is practically not found in steam-heated evaporators), the heat flux increases due to the presence of radiation. For a given liquid at a pressure corresponding to boiling, the nature of the heating surface itself can significantly affect the process (Table PT-5). The data given in the table, obtained in experiments with a single pipe, can be used (as a first approximation) to calculate heat transfer in the presence of a number of immersed pipes, with a clean, uncontaminated surface. [c.213]
This value is somewhat high in terms of noise generation (for heating systems of buildings, the air speed should be below 6.1 msec), but in this case, noise is not a limiting factor. The first approximation can be obtained by substituting this value in the 14th row of the table. 11.4, together with a value of 1.52 m / s for the velocity of the water in the pipes. The latter value was selected based on an acceptable pressure drop across the water side. The mass velocity (line 15) is the product of the values in lines 13 and 14 for air and water, respectively.The heat transfer coefficient is calculated according to the operations indicated in lines 21-27 of the table. We only note that when calculating the value in the 24th line, the heat transfer coefficient from the water side was multiplied by the ratio of the heat exchange surfaces from the water and air sides, respectively. [c.222]
As seen from the table. 15, the heat transfer coefficients for direct-cooled smooth-tube batteries are low and amount to 8-10 kcal m-h-deg). This is due to the low heat transfer coefficient from the air side. [c.182]
Preliminary thermal calculation. If we take into account that the heat transfer coefficient from the condensing steam is large a = = 10 000 W / (m -K), and the pressure loss in nitrogen allows its high velocities in the heat exchanger, it is possible, in accordance with the data in Table. 6.2, take the approximate value of the heat transfer coefficient / C = 150 W / (m K). [c.164]
When calculating the heat transfer coefficient, the values of the heat transfer coefficients are taken, given in table.10. [c.119]
When calculating the heat transfer coefficient, the values of the heat transfer coefficients are used (Table A1.7). [c.106]
As you can see from the table. U-4, sprinkler evaporators with a porous coating turned out to be slightly more economical than smooth-tube ones, although the heat transfer coefficients from the refrigerant side for them are several times higher than for smooth tubes. This seemingly discrepancy is explained by the fact that at low values of the heat transfer coefficient is determined by the thermal resistance of the brine, which is significantly higher than for the refrigerant.In addition, in table. U-4 considered an apparatus with a high cost of pipes (copper-coated copper pipes). [c.139]
In plate evaporators, high values of heat transfer coefficients from the side of the refrigerant. And the coolant provide intensive heat transfer. In fig. 11-11 show the results of the study of heat transfer in models of plate-type evaporators of strip-type and mesh-flow types (see Table 11-3) when using refrigerants K22 and NNz. [c.180]
For flooded boilers of lithium bromide absorption plants, the calculated coefficients of heat transfer from steam to the wall and from the wall to the solution and heat transfer between the steam and the solution are given in Table.43. Thermal resistance of the pipe wall and impurities is taken as 0.000257 m-h-deg kcal. [c.279]
To calculate the heat transfer coefficient of condensing heating steam according to equation (4-49), you need to know the length of the pipes b. According to the table. 4-6 we take approximately the heat transfer coefficient L = 230 W / (m2-K). Then the area of the heat exchange surface will be equal, [c.218]
The values with xz), s (yts), s (Hz), s (1 5i), s (phi) are determined by linear interpolation from tables (see.Calculation passport, table. 2-6). To simplify the algorithm for analyzing iterations, the values of the heat transfer coefficients d (xc, g / c), (l u, phi), (xi, h u), k (Xi hz) are not calculated hereinafter using the criterion equations for the heat transfer coefficients, they are determined linear interpolation according to tables (see Passport of calculation, Tables 7-10), which does not reduce the possibilities of analysis. [c.88]
Scale deposits. When boiling water or aqueous solutions in evaporators heated by condensing steam, the heat transfer coefficients both on the vapor side and on the sp-oron of the boiling liquid with clean surfaces are very large.Hence it follows that even a thin layer of scale can have a very strong effect on the heat transfer coefficient. Pridgen and Badger [76] measured the heat transfer coefficients from condensing vapor to water boiling at 75 ° in a horizontal tubular evaporator. The results are summarized in table. 14-2. These data indicate the significant importance of the total temperature difference, the degree of cleanliness and the nature of the heating surfaces. [c.508]
Thus, kid = 0.616, h = 32BTU / (g // ha -h- ° P) for circular channels.Multiplying by a correction factor equal to the ratio of 3 to 4.3 (Table A3.1), which makes it possible to apply the data for circular channels to triangular channels, we find that for triangular channels on the high pressure side h = 22.5 SHE1 fugp – 4- ° F) [(PO kcal / m -h- ° C)]. The equivalent duct diameter on the low pressure side will be twice as large, as a result of which the heat transfer coefficient decreases to ll, 3BTE / (0i / m -4-F) 155 kcal / m -h- ° C)]. However, the heat exchange surface area will be almost twice as large, therefore, the product M will be approximately the same for gas flows at both low and high pressure.Thus, neglecting the thermal resistance of the wall and assuming that the efficiency of the fins is 100%, we find that the total heat transfer coefficient is approximately 11, BTU / (fg / t -h- ° F) [55 / skal / (l -h- ° C) 1. Using the values mentioned in the previous paragraphs, we obtain an expression for the efficiency of the cross-current [c.195]
The heat transfer coefficient can be calculated if the heat transfer coefficients from the bubbling layer to the wall of the wall element to the cooling agent are known.The latter is determined by known formulas depending on the properties of the cooling agent and its speed. The heat transfer coefficient a from the bubbling layer to the element wall was determined by a number of researchers, the data they obtained are given in table. 37. From these data it follows that the heat transfer coefficient is almost independent of the design of the pipe and the gas velocity (at ω from 0.3 to 3 m / sec). [c.585]
The next task is to find the heat transfer coefficient / s. Since the heat transfer coefficients that determine the value of k are functions of the speeds of movement, then in order to find them, it is necessary to know the cross-sectional area of the channels along which the liquid exchanging heat move (the flow rates are known).This makes it necessary to preset the design and dimensions of the heat exchanger (for this, the normals and catalogs of the exchange equipment are used). The correctness of such a preliminary choice belongs to the field of engineering and is determined by the experience and erudition of the engineer. The preliminary selection is based on an assessment of the heat transfer coefficient, for which you can use table. IV. 2. [c.347]
Flue gases also have a number of disadvantages, due to which it is often necessary to use other, more expensive heat carriers (steam, electric heating, etc.)see below). Flue gases contaminate heat exchange surfaces, as they may contain ash and unburned fuel – soot. Such contamination significantly increases the thermal resistance to the heat transfer process, which, when using flue gases, already has high values, since the heat transfer coefficients from gases to heat exchange surfaces do not exceed 40-60 W / (m K) (see Table 3.1). In addition, flue gases have a very low volumetric heat capacity – about [c.282]
As can be seen from the table. 15, the heat transfer coefficients of smooth-tube batteries are low and amount to 8 — Yuccal / m hour ° C, which is explained by the low heat transfer coefficient from the air side. The heat transfer coefficients of wall-mounted collector batteries from vertical smooth pipes are given in table. 16. [c.149]
The most effective, naturally, turned out to be an apparatus with pipes having both inner and outer ribbing. For an apparatus with five-channel pipes, the heat transfer coefficients when operating on the F-12 turned out to be about 10% lower than when working on the F-22.In fig. 90 presents the coefficients of heat transfer during boiling of F-22 in finned tubes. The best a coefficients were observed for pipes with eight-channel finning, the worst – for smooth pipes. Table 18 shows the experimental data characterizing the pressure drop of the coolant in the ITVR-12.5 apparatus with U-shaped tubes with internal ribbing. The characteristics of the apparatus are given in table. 11 applications. – [c.157]
