A steam power plant operates on a reheated Rankine cycle. Steam enters the high pressure turbine at a pressure of 12.5 MPa and a temperature of 550 ̊C, with a flow rate of 7.7 kg/s and exits at a pressure of 2 MPa. The steam is then heated to 450 C at constant pressure before being expanded in the low pressure turbine and exits the condenser as a saturated liquid at 10 kPa. Since the isentropic efficiencies of the turbine and the pump are 85 percent and 90 percent, respectively; a) degree of dryness, b) net power, c) thermal efficiency of the cycle
