Water vapor at 800 lbf/in.2, 1000 degrees F enters a turbine operating at steady state and expands to 2 lbf/in.2 The mass flow rate is 5.56 lb/s, and the isentropic turbine efficiency is 92%. Stray heat transfer and kinetic and potential energy effects are negligible. Determine the power developed by the turbine, in hp.
