An engineer proposes to have a heat engine that will receive heat from a source at 1000 k and reject heat to a sink at 400 k. the heat engine will produce 500 kw of power aft er receiving 750 kw of heat. this process is possible. a)- true b) false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
