The figure to the right gives the schematic of a vapor power plant in which water steadily circulates through the four components shown. The water flows through the boiler and condenser at constant pressure and through the turbine and pump adiabatically and isentropically. Kinetic and potential energy effects can be ignored. Assume mass flow rate is 2 kg/s. Process data is as follows.
