In an ideal reheated Rankine cycle, water vapor enters the high pressure turbine at a temperature of 400 °C and a pressure of 3 MPa and exits at a pressure of 0.8 MPa. After the water vapor is reheated to 400 °C, it enters the low pressure turbine and expands to a pressure of 10 kPa. a) Find the pump work (kl/kg). b) Find the degree of dryness at the exit of the water vapor from the low pressure turbine. c) Find the turbine work (kJ/kg).
