A one-shell, two-tube pass shell and tube heat exchanger has 1580 tubes with di = 13 mm and do = 16 mm. Tubes have an average length of 6 m per pass. Cold water enters the tubes at 30 C and a rate of 110 kg/s and hot water enters shell at 90 C and a rate of 125 kg/s. Find the rate of heat transfer, ∆TLMTD, and the overall heat transfer coefficient. Use stainless steel tubes and fi = 0.001 m2·K/W. [Ans.: 13 MW, 10.7 C, and 493 W/m2·K].
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
