Steam heated at constant pressure in a steam generator enters the first stage of a supercritical reheat cycle at 28 MPa, 520°C. Steam exiting the first-stage turbine at 6 MPa is reheated at constant pressure to 500°C. Each turbine stage has an isentropic efficiency of 84% while the pump has an isentropic efficiency of 82%. The saturated liquid exits the condenser that operates at a constant pressure of 70 kPa. Determine the quality of the steam exiting the second stage of the turbine and the thermal efficiency.
