A simplified model of the cycle utilized by a heat engine to convert heat into work.
The Carnot efficiency, ηC, is the ratio of the work to the input heat: ηCâÉá
The Carnot Inequality states that the actual efficiency of a system is at best equal to the Carnot Efficiency: η≤ηC.
Heat is the transfer of energy to a system via thermal contact with a reservoir.
At a constant entropy.
At a constant pressure.
At a constant temperature.
Work is the transfer of energy to a system via a change in the parameters of the system.
