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 heat exchanger is being investigated as a waste heat recovery device. A heat exchanger is common device for using a hot fluid to heat a cold fluid without the fluids mixing. The following information is known. The cold fluid stream of liquid A enters at 294.2 K and leaves the device at a temperature of 320.91 K. Liquid A flows at a rate of 0.006 Kg/s and has a specific heat of 4180 J/(Kg K). Liquid B enters the device at a temperature of 350.2 K. Liquid B flows at a rate of 0.005 Kg/s and has a specific heat of 3900 J/(Kg K The dead state is at 293.2 K and 1 bar. The device is adiabatic and the pressure losses are neglected in this problem.
