. A double-pipe counter-flow heat exchanger is to cool ethylene glycol (Cp 2560 J/kg - 'C) flowing at a rate of 3.5 kg/s from 80°C to 40c by water (Cp 4180 J/kg "C) that enters at 20°C and leaves at 55°C. The overall heat transfer coefficient based on the inner surface area of the tube is 250 W/m2 . "C.

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.
