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

34. Fully developed air flows inside the ¼ in tubes of an air-cooled heat exchang-
er at a rate of 1.5 lbm/h. The conditions at the inlet of the tube are atmospheric
pressure and 60 F. After being heated in the 2 ft long tube, air leaves at 780 F.
Find the pressure drop in the heat exchanger.
