A certain coal-fired power plant has a rated power capacity of P = 850 MW. The output of this plant is W = 0.26QH, where QH is the energy input as heat from the hot reservoir. a. Write an equation for the efficiency of a heat engine in terms of QH and the heat QC exhausted to a low-temperature reservoir. b. What's the maximum thermal efficiency of the power plant? c. What's the absolute value of the exhausted heat (QC) each second in MJ for the power plant?
