Steam enters the turbine of a power plant operating on the Rankme cycle (Fig. 8.3) at 600 C and exhausts at 30 kPa. To show the effect of boiler pressure on the performance of the cycle, calculate the thermal efficiency of the cycle and the quality of the exhaust steam from the turbine for boiler pressures of 5.000,7,500, and 10,000 kPa,
