Carnot’s principle: No irreversible engine operating between two reservoirs at constant temperatures can have a greater efficiency than a reversible engine operating between the same temperatures. Furthermore, all reversible engines operating between the same temperatures have the same efficiency.
Carnot’s principle implies that the efficiency of a reversible engine is independent of the working substance of the engine, and therefore van depend only on the temperatures of the hot and cold reservoirs.
Efficiency of Carnot engine = “1 – frac{T_C}{T_H}”
This relation give the maximum possible efficiency for a heat engine operating between two Kelvin temperatures.
