The boiler is heated by the burning of natural gas. The upper pressure is 8 MPa and the condenser temperature is 40C. The turbine inlet temperature at state point 3 is 574C. The feedwater pump and turbine are irreversible with isentropic efficiencies P = 0.85 and T = 0.88, respectively. The steam quality at the exit of the turbine, x4, is 90%. The steam flowrate is 70,000 kg/h. Calculate the power (in kWe) required to drive the feedwater pump.Interpret the answer in term of the total power produced by the turbine(s)
