A turbine with one extraction for regenerative feedwater heating, receives steam with an enthalpy of 3373 kJ/kg and discharges it with an exhaust enthalpy of 2326 kJ/kg. The ideal regenerative feedwater heater receives 11,338 kg/h of extracted steam at 345 kPa (whose h= 2745 kJ/kg). The feedwater (condensate from the condenser) enters the heater with an enthalpy of 140 kJ/kg and departs saturated at 345 kPa (h=582 kJ/kg). Find the work turbine output in kW.
