A steam power plant runs on a reheat Rankine cycle. Steam enters both the high and low pressure turbines at 500oC. The maximum and minimum pressures of the cycle are 10 MPa and 10 kPa, respectively. Steam leaves the condenser as a saturated liquid. The moisture content of the steam at the exit of the low-pressure turbine is 4% if the actual expansion process is adiabatic; 8.5% if the ideal expansion process is isentropic. The isentropic efficiencies of the high-pressure...
