One of the most efficient engines ever built is a coal-fired steam turbine engine in the Ohio valley, driving an electric generator as it operates between 1870 degree C and 430 degree C. Its actual efficiency is 42.0%. How much mechanical power does the engine deliver if it absorbs 1.40 Times 105 J of energy each second from the hot reservoir? kWExplanation / Answer
42/100 * 1.4*10^5 J/s = 58800 J/s = 58800 W
= 58.8 kW
