- Mot water is used to heat air in a double-pipe heat exchanger as shown in the following sketch. If the heat transfer coefficients on the water side and on the air side are 550W/m2Kand55W/m2K respectively, calculate the overall heat transfer coefficient based on the outer diameter. The heat exchanger pipe is 5-cm, schedule 40 steel (k=54W/mK) with water inside.Water flowing in a long, aluminum lube is to be heated by air flowing perpendicular to the exterior of the tube. The ID of the tube is 1.85 cm, and its OD is 2.3 cm. The mass flow rate of the water through the tube is 0.65kg/s, and the temperature of the water in the lube averages 30C. The free-stream velocity and ambient temperature of the air are 10m/sand120C, respectively. Estimate the overall heat transfer coefficient for the heat exchanger using appropriate correlations from previous chapters. State all your assumptions.1 please explain well in type form thank you Why does a “mixed” or “unmixed” fluid arrangement influence heat-exchanger performance?
- For Heat transfer through cylinder tube wall, the temperature is to be a linear function of r (radius) of the tube. Select one: O True O False The conductivity of H20 in solid form (ice) is higher than that of H20 in liquid form (water). Select one: O True O False F, (Correction factor for temperature in some heat exchangers) should be 1.0 or greater than 1.0 in some cases. Select one: O True FalseDue higher viscosity, the heat-transfer coefficient of moving liquid hydrocarbons is generally higher than that of moving water Select one: O True O False The proper strategy to enhance heat transfer of a heat exchanger is trying to increase the heat transfer coefficient of the side with the lower heat resistant. Select one: O True O False For the universal 3-D heat transfer equation (see topic 7 in URCourses notes), we have to simplify by eliminating terms that are zero or near zero first, and then we can only use numerical methods (such as finite difference) to solve those problems. Select one: O True O Falsecan you please give me an analysis of heat transfer in heat exchangers as like a text ?

The heat exchanger is insulated by a 130-mm glass fiber insulation (paper faced, 28 kg/m³). The heat transfer coefficients of water and oil are 1200 and 900 W/m² °C, respectively. 2 m Ts cm S cm 5 cm OIL Water Figure 1: A parallel-flow-plate-type heat exchanger.

- Nanofluids are at the spot of consideration for new generation of heat exchangers. As a process engineer working at solar power system, you were assigned to design a novel heat exchanger and you was advised to use nanofluids. Which nanofluid you will use? What are the expected heat transfer enhancement? what are the expected challenges?When can the conductive thermal resistance of the tube in a heat exchanger be neglected in overall heat transfer coefficient calculation? Never When the tube is thin or the material is highly conductive When the tube is thin. When the tube material is highly conductive. Which of the following sentence(s) is/are true? We cannot calculate thermal resistance of a solid slab. Thermal resistance concept is applicable only in Cartesian or Cylindrical coordinate. We cannot calculate thermal resistance of a solid cylinder. To apply thermal resistance concept, a problem only needs to be one dimensional and steady.what overall thermal system is this for in reference to part 1 , also could you also use numbers from a source for part 2 and do the calculations that way with actual reliable numbers , to make things easier to understand. And also part 2 is not complete as you need to complete performance optimisation of heat exchangers.
