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.

Hot gas enters a finned-tube, crossflow heat exchanger at 300 °C and exits at 100 °C. Assume that both fluids are unmixed. The gas is used to heat pressurized water flowing at 1 kg/s from 35 °C to 125 °C. Assume constant properties and use 1000 J/kg K and 4197 J/kg K as the specific heat of the gas and the water, respectively.
