8.22 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 78% while the pump has an isentropic efficiency of 82%. Saturated liquid exits the condenser that operates at constant pressure, p. a. For p = 6 kPa, determine the quality of the steam exiting the second stage of the turbine and the thermal efficiency. 0.9330. 36.06%

Transcribed Image Text:8.22 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 78% while the pump has an isentropic efficiency of 82%. Saturated liquid
exits the condenser that operates at constant pressure, p.
a. For p = 6 kPa, determine the quality of the steam exiting the second stage of the
turbine and the thermal efficiency. 0.9330, 36.06%
