CARNOT CYCLES - University Of Colorado Boulder
Sadi Carnot was a French physicist who proposed an “ideal” cycle for a heat engine in 1824. Historical note – the idea of an ideal cycle came about because engineers were trying to develop a steam engine (a type of heat engine) where they could reject (waste) a minimal amount of heat. ... Fetch Doc
