A steam power plant operates on the reheat Rankine cycle. Steam enters the high-pressure turbine at 12.5 MPa and 5508C at a rate of 7.7 kg/s and leaves at 2 MPa. Steam is then reheated at constant pressure to 400 C before it expands in the low-pressure turbine. Steam leaves the condenser as a saturated liquid. The exit of the turbine is saturated at the condenser pressure (a) the condenser pressure, (b) the net power output, and (c) the thermal...
