Consider an ideal Rankine cycle using water with a high-pressureside of the cycle at a supercritical pressure. Such a
cycle has a potential advantage of minimizing local temperaturedifferences between the fluids in the steam
generator, such as the instance in which the high-temperatureenergy source is the hot exhaust gas from a gas-
turbine engine. Calculate the thermal efficiency of the cycle ifthe state entering the turbine is 30 MPa, 550°C, and
the condenser pressure is 5 kPa. What is the steam quality atthe turbine exit?
