Anuclear power plant generates 750 mw of power. the heat engine uses a nuclear reactor operating at 315c as the source of heat. a river is available (at 20c) which has a volumetric flow rate of 165 m/s. if you use the river as a heat sink, estimate the temperature rise in the river at the point where the heat is dumped. assume the actual efficiency of the plant is 60% of the carnot efficiency
