Figure gives the schematic of a water-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. Kinetic and potential energy effects can be ignored. Process data follow: Qin Boiler Turbine We Pump Condenser 3. Process 1-2: constant pressure at 8 bar from x1 = 5% to x2 = 95% saturated liquid to saturated vapor Process 3-4: constant pressure at 1.5 bar from x3 = 95% to x4 = 25% saturated liquid to saturated vapor
