A shell and tube heat exchanger with one shell pass and two tube passes is used to heat 8.82 kg/s of fluid from 15.6 °C to 60 °C by using saturated steam at 150 kPa. The steam is condensing on the outside of the tubes with h= 15 kW/m2.K. There are 50 tubes with an outside diameter of 1.91 cm and a wall thickness of 0.211 cm. If the fouling coefficient on the inside of the tubes is 5678 W/m2.K,...
A shell and tube heat exchanger with one shell pass and one tube pass will be used to condense the steam to saturated liquid, which enters the shell side as a saturated vapor at 400 K. The tube side contains R-134a refrigerant with an inlet temperature of 300 K and a mean velocity of 0.4 m/s. The steam flow rate is 1.5 kg/s. The tubes are made from AISI 302 stainless steel and have a 1" nominal diameter (Di =...

heat transfer Test Yourself A Shell-and-tube heat exchanger, consisting of a single shell and 30.000 tubes, each executing two passes, is used in a large steam power plant to condense steam to liquid water. The steam condensed in the shell side of the heat exchanger with an associated convection coefficient (h) of 11.000 W/m2.°C. The heat transfer rate through the heat exchanger (O is 2x10' W. Cooling water is passing through a thin tubes with D = 2.5 cm, at...
(LMTD method) A 2 shell, 4 tube pass heat exchanger is being used to heat 40 kg/s of a process fluid in the tubes from an inlet temperature of 15°C to a target temperature of 70°C using condensing steam at 150°C. The overall heat transfer coefficient for a clean heat exchanger was Uo=1500W/m2.°C, however, the design engineer neglected to take into account fouling of the heat exchanger. After 5 years of use, fouling has occurred with fouling factors of 0.0005m2.°C/W...
Question 5 - LMTD Heat Exchangers A 2 shell, 4 tube pass heat exchanger is being used to heat 50 kg/s of a process fluid in the tubes from an inlet temperature of 25°C to a target temperature of 80°C using condensing steam at 150°C. The overall heat transfer coefficient for a clean heat exchanger was U-1500W/m2.°C, however, the design engineer neglected to take into account fouling of the heat exchanger. After 5 years of use, fouling has occurred with...
Section C – shell and tube heat exchanger sizing The vapour condenser for the combined gas-steam power cycle described in Section B heats river water from 15 °C to 18 °C. The condenser is a shell and tube heat exchanger with one shell pass and two tube passes. The cooling water is inside the tubes while the shell side has the condensing vapour. More details: a. The tube OD is 1 ¼” (inches), the tube wall thickness is 0.05 inches....
6. A shell-and-tube heat exchanger with 2-shell passes and 12-tube passes is used to heat water (c 4,180 J/kg K) flowing at a rate of 4.5 kg/s in the tubes from 20°C to 70°C. Heat is supplied by hot oil (cp 2300 J/kg K) that enters the shell side at 170°C at a rate of 10 kg/s. If overall heat transfer coefficient on the tube-side is 350 W/m-K, determine the heat transfer surface area on the tube side.
be clear Problem 3 (60 Points). A 1-2 shell-and-tube heat exchanger must be designed to heat 2.5 kg/s of water from 15 to 85°C. The heating is to be accomplished by passing hot engine oil at a rate of 5.2 kg/s, which is available at 160°C, through the shell side of the exchanger. The oil is known to provide an average convection coefficient of 400 W/m2K on the outside of the tubes. Ten tubes passes the water through the shell....
