A steam Rankine cycle operates between the pressure limits of 1500 psia in the boiler and 3 psla in the condenser. The turbine Inlet temperature is 800°F. The turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to produce 2500 kW of power. How much error is caused in the thermal efficiency if the power required by the pump were completely neglected? Use steam tables. The error caused in the thermal efficiency if the power required by the pump was completely neglected is 32.65 %.

Transcribed Image Text:A steam Rankine cycle operates between the pressure limits of 1500 psia in the boiler and 3 psia in the condenser. The turbine
Inlet temperature is 800°F. The turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to
produce 2500 kW of power. How much error is caused in the thermal efficiency if the power required by the pump were
completely neglected? Use steam tables.
The error caused in the thermal efficiency if the power required by the pump was completely neglected is 32.65 %.
