Calculate the required area of an air-to-air heat exchanger to cool 20,000 cfm of air from 1200 oF to 400 oF. Assume ambient air at 80 oF will be heated to 800 oF by the exchange, Assume heat losses are 10% and that the overall heat transfer coefficient is 1.0 Btu/hr-ft2-oF.
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.
