Maximum Efficiency Of Heat Engine

Maximum Efficiency Of Heat Engine. This shows that the efficiency of an ideal heat engine depends only on the temperatures of the source and sink, and also that a heat engine can never be 100 per cent efficient. The maximum thermal efficiency of a heat engine is the thermal effeciency of a carnot heat engine as given by the following :
