8.33 Steam heated at constant pressure in a steam generator enters the first stage of a supercritical reheat cycle at 28 MPa, 5208C. Steam exiting the first-stage turbine at 6 MPa is reheated at constant pressure to 5008C. Each turbine stage has an isentropic efficiency of 78% while the pump has an isentropic efficiency of 82%. Saturated liquid exits the condenser that operates at constant pressure, p. (a) For p 5 6 kPa, determine the quality of the steam exiting the second stage of the turbine and the thermal efficiency.
