Consider a simple ideal Rankine cycle using water at a supercritical pressure. Such a cycle has the potential advantage of minimizing local temperature differences between the fluids in the steam generator, such as when the high-temperature energy source is the hot exhaust gas from a gas turbine engine. Calculate the thermal efficiency of the cycle if the state entering the turbine is 8000 lbf/in.², 1300 F and the condenser pressure is 0.95 lbf/in.². What is the steam quality at the turbine exit?
