A power plant is designed to generate 8.0 MW OF WORK 98.0X106 J/s) . The plant is powered by steam at 765K with the exhaust at 341K . If this power plant has an efficiency of 49% of the efficiency of an ideal engine operating at the same temperatures , what is the magnitude of the heat that is exhausted by the engine each second ?
give your answer in MW(106 J/s) to three significant figures . it is a positive number ( the magnitude ).
