A fossil-fuel steam power plant operates at about 50% of Carnot thermal efficiency. It has been suggested that the air pollution from a plant that operates at 1000 F would contribute 1/2 the pollution (per ton of coal burned) that the present system that operates at about 1500 F. The heat rejection temperature is 70 F. For the same electrical output what is the percent difference in the pollution resulting from the combustion? Assume that the thermal energy released by...

A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high-pressure steam at 320 ∘C. The steam spins a turbine, which produces 1000 MW of electric power, then the steam is condensed and the water is cooled to 25∘C before starting the cycle again. Part A: What is the maximum possible thermal efficiency of the power plant? Part B: Cooling water from a river...
