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.

Question

A heat exchanger has an over-all coefficient of heat transfer of 900 W/m2-K. The mean temperature difference is 20C and heat loss is 15,000 W. Calculate the heat transfer area.
