01) An inventor claims to have developed a heat engine that receives 700Kj of heat from a source at 500K and produces 300Kj of net work while rejecting the waste heat to a sink at 290K. is this reasonable claim?
The maximum heat efficiency of the engine is the Carnot efficiency;
Since efficiency is defined as;
Therefore it is impossible to have a work output greater than 294kJ and therefore the inventors claim is not reasonable.
