A cross-flow heat exchanger is used to transfer heat from a stream of saturated water at  100 °C to a stream of air entering at 40 °C. The UA value of the heat exchanger is 5000 W/K.  Develop an equation for the outlet temperature of the air as a function of the mass flow rate of air through the heat exchanger. Plot the outlet air temperature vs. mass flow rate of air from 0.5 kg/s to 20 kg/s

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.
