Question:

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 4508C before it expands in the low-pressure turbine. The isentropic efficiencies of the turbine and the pump are 85 percent and 90 percent, respectively. Steam leaves the condenser as a saturated liquid. If the moisture content of the steam at the exit of the turbine is not to exceed 5 percent, determine
(a) The condenser pressure,
(b) The net power output, and
(c) The thermal efficiency.
