A steam engine takes in superheated steam at T, = 270°C = 543K and discharges condensed steam at T. 50°C = 323K. Its efficiency is e = 30%. %3D a) How does this efficiency compare with the maximum possible efficiency? b) If the useful power output of the engine is 200 kW, how much heat does the the engine discharge to its surroundings in 1 hour?
