Serway & Jewett — Heat Engines, Entropy, and the Second Law of Thermodynamics: Problem 7
One of the most efficient heat engines ever built is a coal-fired steam turbine in the Ohio River valley, operating between $1\,870^{\circ}\text{C}$ and $430^{\circ}\text{C}$. (a) What is its maximum theoretical efficiency? (b) The actual efficiency of the engine is $42.0\%$. How much mechanical power does the engine deliver if it absorbs $1.40 \times 10^5\text{ J}$ of energy each second from its hot reservoir?
