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.

Question

Consider a heat exchanger in which both fluids
have the same specific heats but different mass flow rates.
Which fluid will experience a larger temperature change: the
one with the lower or higher mass flow rate?
