A Carnot engine has a power output of 150 kW. The engine operates between two reservoirs at 20.0 °C and 500 °C. a) How much heat QH does the plant consume per second? b) What is the heat Q, released by the plant per second? c) What is the (Carnot) efficiency nc of this power plant? d) If there were irreversibilities in the power plant, but its power output were the same, how would this affect the heat released to the river per second? Explain.
