Carnot cycle: 5

5. Carnot theorem is a principle that limits the maximum efficiency for any possible engine. The efficiency solely depend Carnot's theorem states: All irreversible heat engines between two heat reservoirs are less efficient than a Carnot engine operating between the same reservoirs. ually efficient with a Carnot e ηmax = ηCarnot = 1−Tc / TH ... Carnot Cycle - HyperPhysics ... Carnot Cycle Because the Carnot heat engine cycle is an ideal cycle consisting of only reversible processes, it produces the maximum power output and has the maximum thermal efficiency among all heat engines operating between the same heat source at T H and the same heat sink at T L. In TQ 9 of Unit 7, you have obtained expression for the work done in Carnot cycle depicted on an indicator diagram. We will extend this result to calculate the efficiency of Carnot engine and show that no engine can be more efficient than a Carnot engine. As mentioned earlier, thermodynamics is a phenomenological science and its laws need no proof. In fact, the second law of thermodynamics has been stated in two different but equivalent forms by Kelvin-Planck and Clausius. You will learn ...
