Question
Transcribed Image Text:A simple Rankine cycle uses water as the working fluid. The boiler operates at 6000 kPa and the condenser at 50 kPa. At the entrance
to the turbine, the temperature is 450°C. The isentropic efficiency of the turbine is 94 percent, pressure and pump losses are
negligible, and the water leaving the condenser is subcooled by 6.3°C. The boiler is sized for a mass flow rate of 19 kg/s. Determine
the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the
thermal efficiency. Use steam tables.
The rate at which heat is added in the boiler is 4192.12 kW.
The power required to operate the pumps is 59354.47 kW.
The net power produced by the cycle is -55162.35 ✪ kW.
The thermal efficiency of the cycle is 13.16 %.
