Carnot cycle - Wikipedia

WebHeat transfer in the Carnot cycle occurs at zero temperature differential, an impossibility in the real world. For heat to transfer from one fluid to another, there must be a temperature difference, one fluid hotter than the other. During the heat transfer process no work is performed between the two fluids. One is simply increasing the ... WebAll heat transfer processes are isothermal. Carnot's Theorem. Carnot's theorem, also known as Carnot's rule, or the Carnot principle, can be stated as follows: ...

WebWe know that internal energy is a state variable, which means the internal energy at point A will always be the same regardless of the path that leads to point A. Therefore, there is no change in internal energy when a Carnot cycle is completed, because we started at point A and finished at point A. WebFigure 15.21 shows the PV PV diagram for a Carnot cycle. The cycle comprises two isothermal and two adiabatic processes. Recall that both isothermal and adiabatic processes are, in principle, reversible. Carnot also determined the efficiency of a perfect heat engine—that is, a Carnot engine.
