A certain coal-fired power plant has a rated power capacity of P = 955 MW. The output of this plant is W = 0.39QH, where QH is the energy input as heat from the hot reservoir. Which would increase the efficiency more, doubling QH or reducing QC by half? Doubling Qh would bring about the greater increase in efficiency. Doubling Qh and reducing Qc by half will have the same effect in increasing the efficiency. Neither doubling Qh and reducing Qc by half would change the efficiency. Both doubling Qh and reducing Qc by half would reduce the efficiency. Reducing Qc by half bring about the greater increase in efficiency.
