Consider a steam power plant that operates on the ideal regenerative Rankine cycle with a closed feedwater heater. The plant maintains the turbine inlet at 3000 kPa and 350 deg C; and operates the condenser at 10 kPa. Steam is extracted at 1000 kPa to serve the closed feedwater heater, which discharges into the condenser after being throttled to condenser pressure. The temperature of the feedwater entering the boiler is 210 deg C. a.)Calculate the work produced by the turbine in kJ/kg. b.)Calculate the work consumed by the pump in kJ/kg. c.)Calculate the heat supply in the boiler for this cycle per unit of boiler flow rate in kJ/kg. d.)Calculate the cycle thermal efficiency in %.
