A shell-and-tube heat exchanger consists of a single shell and 10,000 tubes of 35 mm diameter, each executing two passes. The heat exchange is accomplished by passing the cold fluid ( Cc=1.05x107W/K) entering at 25°C through the thin-walled tubes and leaving at 42°C. The hot fluid (Ch=14x106W/K) is entering at 62°C and the overall heat transfer coefficient U is equal to 3000 W/m2.K. What is

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.
