cross-flow heat exchanger with one fluid mixed (cool air) and an air flow rate of 0.75 kg/s for the hot air and 0.563 kg/s for
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.
An air-to-air recovery unit uses a cross-flow heat exchanger with one fluid mixed (cool air) and an air flow rate of 0.75 kg/s for the hot air and 0.563 kg/s for the hot air and 0.563 kg/s for the cool air. The hot air enters at 405 C while the cool air enters at 25 C. Calculate the exit temperatures of (a) the hot air (1 dp) and (b) the cool air (1 dp) for, U=50 W/m2-K and a total heat exchanger area of 17 m2
