(III) At a steam power plant, steam engines work in pairs, the output of heat from one being the approximate heat input of the second. The operating temperatures of the first are 670^∘ C and 440^∘ C , and of the second 430^∘ C and 290^∘ C . If the heat of combustion of coal is 2.8 ×10^7 J / kg , at what rate must coal be burned if the plant is to put out 1100 MW of power? Assume the efficiency of the engines is 60% of the ideal (Carnot) efficiency. | Numerade

$SOLVED:(a) At a steam power plant, steam engines work in pairs, the heat output of the first one being the approximate heat input of the second. The operating temperatures of the first are 710^{\circ} \mathrm{C} and 430^{\circ} \mathrm{C}, and of the second 415^{\circ} \mathrm{C} and 270^{\circ} \mathrm{C} . If the heat of combustion of coal is 2.8 \times 10^{7} \mathrm{J} / \mathrm{kg}, at what rate must coal be burned if the plant is to put out 950 \mathrm{MW} of power? Assume the efficiency o$
