Across-flow exchangerwith both fluids unmixedand an airflow rate of 0.5 kg/s on bothsides. The hot air enters at 350oC while thecool air enters at 20oC. Calculate the exit temperatures for U = 60 W/m2· oC anda total exchanger area of 15 m2.What would be the exittemperatures if the flow rates were cut in half, assuming no change in U? What if the flow rates weredoubled?
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.
