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.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
