A steam thermoelectric plant operates a Rankine cycle withoverheating. Water enters the pump as saturated liquid , 7.7 kg/s.The efficiency of the pump is 0.9 The water enters the highpression turbine at 12 500 kPa and 550°C, after that steamoverheats at a constant pressure of 2000 kPa until 450°C before itexpands on the low pressure turbine. The efficiency of bothturbines is 0.85. The vapor quality when it enters to the condenseris 0.95 Determine the thermal efficiency of the cycle.
