"A Very Brief History of Thermodynamics". What is Carnot’s theorem Carnot’s theorem also known as Carnot’s rule was developed by Nicolas Léonard Sadi Carnot in the year 1824, with the principle that there are limits on maximum efficiency for any given heat engine.

The maximum efficiency is the ratio of the temperature difference between the reservoirs and the temperature of the hot reservoir, expressed in the equationĪnd the reference temperature T 1 has the value 273.16. Every Carnot heat engine between a pair of heat reservoirs is equally efficient, regardless of the working substance employed or the operation details. The simplest way to prove this theorem is to consider the scenario shown below, in which we have an irreversible engine as well as a reversible engine operating between the reservoirs T H and T LH from the high temperature. The efficiency of a Carnot engine depends solely on the temperatures of the hot and cold reservoirs.Ĭarnot's theorem states that all heat engines between two heat reservoirs are less efficient than a Carnot heat engine operating between the same reservoirs. Carnot’s theorem, also known as Carnot’s rule, or the Carnot principle, can be stated as follows: No heat engine operating between two heat reservoirs can be more efficient than a reversible heat engine operating between the same two reservoirs.
