Consider a steam power cycle in which saturated water vapor at 25 bar (State 1) enters an adiabatic steam turbine. At the exit of the turbine, steam leaves at 0.1 bar with 80% quality (State 2). Saturated liquid water at 0.1 bar (State 3) exits the condenser. Water is pumped to 25 bar and 50?C (State 4) in an adiabatic pump.
(a) Calculate thermal efficiency (%) of the cycle.
(b) Is the Clausius inequality satisfied? Provide quantitative justification.
