Heat Engines - mpoweruk.c

2018-11-20 · Heat Engine Efficiency. Carnot showed that the maximum efficiency η which can be achieved from a heat engine is given by: η = (T h - T c)/T h or η = 1 - T c /T h. Efficiency Notes . The efficiency can be improved by maximising the difference between the hot inlet and cold exhaust temperatures of the working fluid during the heat cycle.
