Consider a nuclear power plant that produces 1200 MW of power and has a conversion efficiency of 34 percent (that is, for each unit of fuel energy used, the plant produces 0.34 units of electrical energy. Assuming continuous operation, determine the amount of nuclear fuel consumed by the plant per year. Hint: You will have to find out how much energy nuclear fuel produces.

A car engine whose output power is 145 hp operates at about 16 % efficiency. Assume the engine's water temperature of 79 ∘C is its cold-temperature (exhaust) reservoir and 495 ∘C is its thermal "intake" temperature (the temperature of the exploding gas-air mixture). What is the ratio of its efficiency relative to its maximum possible (Carnot) efficiency? Estimate how much power (in watts) goes into moving the car. How much heat, in joules and in kcal, is exhausted to the...
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...
