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.

Steam (H2O) enters a turbine at 35 m/s and specific enthalpy of 3500 kJ/kg. Thesteam leaves the turbine as a mixture of vapor and liquid having a velocity of 60m/s and a specific enthalpy of 2400 kJ/kg. If the flow through the turbine is steady,adiabatic, and changes in elevation are negligible, calculate the work output per unitmass (kJ/kg) for the turbine.
