QUESTION 1 A steam power plant operates on a simple ideal Rankine cycle. The boiler operates at 10,000 kPa and 500 °C. The condenser operates at 10 kPa. The power output of the cycle is 175 MW. The turbine operates with an isentropic efficiency of 0.80, while the pump operates with an isentropic efficiency of 0.90. Estimate the thermal efficiency of the cycle and the heat transferred in the condenser. Thermal efficiency of the cycle = % Heat transferred in the condenser = kJ/kg
