Concept explainers

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.

A steam condenser operates at 61 cm of Hg vacuum. The steam enters the condenser with a moisture content of 87%. Cooling water is supplied to the condenser at a temperature of 20 C with a terminal difference of 5 C.
