A mechanical engineer claims that he inspected a heat engine and found the following information. The heat engine receives heat from a heat source at 1200 oC and rejects heat to a heat sink at 500 oC. The heat engine produces 500 kJ of work and has a thermal efficiency of 40%. Is this heat engine possible? Why? Determine the heat supplied to this engine by the heat source. Determine the heat rejected to heat sink.
