A shell-and-tube heat exchanger with one shell passand 20 tube passes uses hot water on the tube side toheat oil on the shell side. The single copper tube hasinner and outer diameters of 20 and 24 mm and alength per pass of 3 m. The water enters at 87°C and0.2 kg/s and leaves at 27°C. Inlet and outlet temperatures of tile oil are 7 and 37°C. What is the averageconvection coefficient for the tube outer surface?

- 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.arrow_forwardWhat is the main difference between a copper and a cupronickel coaxial heat exchanger, and where is each used?arrow_forwardPART 4The following represents a parallel heat exchanger which contains 130 tubes each with a diameter of 48mm and 1.6 m long with thin walls of steel. Investigate how much hot water can be produced and how much hot gas will be needed.Using the data below determine the flow rate of water and gas for parallel and contra flow configurations and compare them.The water needs to be heated from 15oC to 95 oCThe surface heat transfer coefficient for the water = 1500 W/m2 KThe specific heat capacity of the water is 4.19 kJ/kg K. The gas temperature at inlet = 350oC and may be cooled to 120oCThe surface heat transfer coefficient for the gas = 300 W/m2 KMean specific heat of the gasses cp = 1.13 kJ/kg K.The wall is thin so the temperature drop due to conduction is negligible.arrow_forward
- A single-shell, four-tube-pass heat exchanger is used to cool water flowing at 14 kg.s¹ entering at 18°C using ammonia with a mass flow rate of 18 kg.s¹ and an entry temperature and pressure of -12°C and 650 kPa, absolute, respectively. The heat exchanger is to use the ammonia in the liquid form, so no evaporation can be allowed. At 620 kPa, absolute pressure, ammonia evaporates at 10.5°C. The overall heat transfer coefficient of the heat exchanger is 568 W.m2 and the heat transfer surface area is 75 m². Determine the outlet temperatures of the hot and cold streams. Identify whether the heat exchanger, operating under the conditions shown, satisfies the rec irement that the ammonia remains liquid throughout the process.

Water flows in the tubes, entering at 35oCand leaving at85oC. The overall heat-transfer coefficient for this arrangement is 900W/m2·oC.The exchanger is a shell tube with two shell passes and two tube passes.Calculate the following: a) The water exit temperature if flow rate of glycol to the exchanger is reduced in half with the entrance temperatures of both fluids remaining the same and by how much is the heat-transfer rate reduced?; b) The percentage reduction of heat transfer if water-flow rate is reduced by 25percent,while the gas flowrate is maintained constant along with the fluid inlet temperatures. Assume that the overall heat-transfer coefficient remains the same; andc) The flow rate of water required andthe area of the heat exchanger;arrow_forwardA two pass steam surface condenser is to be designed to condense 10000 kg/hr of steam having an enthalpy of 2240 kj/kg. Condenser pressure is 13.79 kpa. circulating water enters the condenser at 25 C and leaves at 40 C. the outside and inside diameter for a water tube, OD=20 mm, ID = 17 mm and water velocity of 3 m/s. if the overall coefficient of the heat transfer is 14100 kj/hr-m-C of outside tube surface, determine the amount of circulating water in m/hr.arrow_forward
