Example (5): Gases expand in a propulsion nozzle from 3.5 bar and 425 C down to a back pressure of 0.97 bar, at the rate of 18 kgis. Tacking a coefficient of discharge of 0.99 and a nózzle efficiency of 0,94, calculate the required throat and exit areas of the nozzle. For the gases take y =1.333 and Cp 1.1lkJ/kg K. Assumie that the inlet velocity is negligible.

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.
