Steam enters the turbine of a power plant operating on the Rankine cycle at 3300kPa and exhausts at 50kPa. To show the effect of superheating on the performance of the cycle,
(1) calculate the thermal efficiency of the cycle and the quality of the exhaust steam from the turbine for turbine-inlet steam temperatures of 450℃, 550℃, 650℃;
(2) Illustrate and Explain the results with the first and second laws of thermodynamics.
