Coefficient of performance of carnot engine

WebCoefficient of performance of the refrigerator working between the same source and the sink will be Q. The efficiency of Carnots heat engine is 0.5 when the temperature of the source is T 1 and that of sink is T 2 . WebThe Carnot Efficiency is the theoretical maximum efficiency one can get when the heat engine is operating between two temperatures: The temperature at which the high temperature reservoir operates ( T Hot).; The temperature at which the low temperature reservoir operates ( T Cold).; In the case of an automobile, the two temperatures are:
