Definition

efficiency determined by the quotient of the temperatures of the hot source and the cold sink:

η_{max} = 1 - \frac{T_{c}}{T_{h}}

where $T_{c}$ is the thermodynamic temperature (thermodynamic temperature) of the cold sink and $T_{h}$ is the thermodynamic temperature (thermodynamic temperature) of the hot source

rendement déterminé par le quotient de la température de la source chaude par la température de la source froide:

η_{max} = 1 - \frac{T_{c}}{T_{h}}

où $T_{c}$ est la température thermodynamique (thermodynamic temperature) de la source froide et $T_{h}$ est la température thermodynamique (thermodynamic temperature) de la source chaude

Notes

An ideal heat engine operating according to the Carnot process is delivering the maximum efficiency.

Un moteur thermique idéal fonctionnant selon le processus de Carnot fournit le rendement de Carnot.
