1991B3 (modified) A heat engine consists of an oil-fired steam turbine driving an electric power generator with a power output of 120 megawatts. The thermal efficiency of the heat engine is 40 percent.
(a) Determine the time rate at which heat is supplied to the engine.
(b) If the heat of combustion of oil is `4.4×107` joules per kilogram, determine the rate in kilograms per second at which oil is burned.
(c) Determine the time rate at which heat is discarded by the engine.
