Consider a simple ideal Rankine cycle which uses water as theworking fluid. The boiler pressure is 6100 kPa and the condenserpressure is 30 kPa. At the turbine inlet, steam is at 480°C. Theisentropic efficiency of the turbine is 92 percent. The pump lossesare negligible and the water leaving the condenser is subcooled by6.3°C. The boiler is sized for a mass flow rate of 20 kg/s.Determine the following values.
The temperature at the pump inlet.
°CThe specific volume at the pump inlet.
m3/kgThe specific enthalpy at the turbine exit.
kJ/kgThe rate at which heat is added in the boiler.
kWThe power required to operate the pumps.
kWThe net power produced by the cycle.
kW
The thermal efficiency.
