Steam enters the turbine of a steam power plant that operates on a simple ideal Rankine cycle at a pressure of 6 MPa, and it leaves as a saturated vapor at 7.5 kPa. Heat is transferred to the steam in the boiler at a rate of 55000 kJ/s. Steam is cooled in the condenser by the cooling water from a nearby river, which enters the condenser at 15C.Determine the net power output in kW if the thermal efficiency of the cycle is 48.57%.
