0.8 kg/s of water enters the tube from a type 2 shell-pass, 4 tube-pass heat exchanger at 17˚C and leaves the tube at 37˚C. This water is used to cool the air entering the shell at a temperature of 250˚C. U=432 W/m2.˚C. Define a. The temperature of the air coming out of the heat exchanger b. The area of the heat exchanger required. c. Heat exchanger effectiveness d. After using the heat exchanger for 5 years, it occurs causing an increase in the thermal resistance value of Rf = 0.0005 m2.˚C/W. Calculate what is the temperature of the air coming out of the heat exchanger now?
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.
