Maximum Carnot efficiency =
Maximum endoreversible efficiency =
Calculates the theoretical maximum efficiency of a heat engine, given a heat source at one temperature and a heat sink at another temperature, using Carnot's well-known equation and also a far less known but far more accurate equation based on endoreversible thermodynamics.
Endoreversible thermodynamics modifies Carnot's assumptions to acknowledge that the heat transfers within the engine will never match the reversible ideal. For more information see the Wikipedia webpages on "Heat engine" and "Endoreversible thermodynamics." This acknowledgement brings the resulting equation into better alignment with reality, making the estimates of maximum efficiency much more accurate and useful.
