Question
The figure shows the schematic of a vapor power plant in which 100 kg/s of water circulates through the four components operating at steady state. 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:
Process 4–1: constant-pressure at 4000 kPa from saturated liquid to saturated vapor.
Process 2–3: constant-pressure at 20 kPa from x2 = 88% to x3 = 18%.
Process data follow:
Process 4–1: constant-pressure at 4000 kPa from saturated liquid to saturated vapor.
Process 2–3: constant-pressure at 20 kPa from x2 = 88% to x3 = 18%.
Determine the cycle thermal efficiency. Determine σ˙cycle, in kW/K. Determine if the cycle is internally reversible, irreversible, or impossible.
