Consider a steam power plant that operates on the ideal regenerative Rankine cycle with a closed feedwater heater as shown in thefigure. The plant maintains the turbine inlet at 3000 kPa and 350°C and operates the condenser at 25 kPa. Steam is extracted at 1000kPa to serve the closed feedwater heater, which discharges into the condenser after being throttled to condenser pressure. Calculatethe work produced by the turbine, the work consumed by the pump, and the heat supply in the boiler for this cycle per unit of boilerflow rate.

Consider a steam power plant that operates on the ideal regenerative Rankine cycle with a closed feedwater heater as shown in the
figure. The plant maintains the turbine inlet at 3000 kPa and 350°C and operates the condenser at 25 kPa. Steam is extracted at 1000
kPa to serve the closed feedwater heater, which discharges into the condenser after being throttled to condenser pressure. Calculate
the work produced by the turbine, the work consumed by the pump, and the heat supply in the boiler for this cycle per unit of boiler
flow rate. Use steam tables.
