Extracted text: A steam power plant operates on the reheat Rankine cycle. Steam enters the high-pressure turbine at 8 MPa and 500°C at a rate of 7.7 kg/s and leaves at 3 MPa. Steam is then reheated at constant pressure to 450°C before it expands to 20 kpa in the low-pressure turbine. The isentropic efficiencies of the turbine and the pump are 85 percent and 90 percent, respectively. Steam leaves the condenser as a saturated liquid. Draw the cycle on T-s diagram and determine the thermal efficiency.
