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

10.
A liquid to liquid counterflow heat exchanger is used to heat a cold fluid from 130°F
to 320°F. Assuming that the hot fluid enters at 600°F and leaves at 500°F, calculate
the log mean temperature difference for the heat exchanger.
