The Carnot efficiency can be expressed as μC = (Ti - To) / Ti (1) Importance of a Carnot cycle is that it will define the maximum possible efficiency of a heat engine cycle working between two temperature limits. There will not be any heat engine, which will be more efficient than the Carnot cycle working between same temperature limits. Carnot heat engine and all other heat engines follow the second law of thermodynamics. The second law of thermodynamics is correlated with the spontaneous and non-spontaneous processes. In a simple way, you can say that by the study of 2nd law you may tell more about the spontaneous and non-spontaneous process. In this process the surroundings do work on the gas.

We can check the efficiency by computing the ratio of net work to the heat input .Doing this gives, not surprisingly, the same value as the Carnot equation. For a cycle with adiabatic efficiencies of pump and turbine both equal to 0.8 (non-ideal components), the efficiency and work ratio can be found as follows. 2011-11-22 · Overview The Carnot Cycle is an entirely theoretical thermodynamic cycle utilising reversible processes. The thermal efficiency of the cycle (and in general of any reversible cycle) represents the highest possible thermal efficiency (this statement is also known as Carnot's theorem - for a more detailed discussion see also Second Law of Thermodynamics). Figure 5 - An ideal Stirling engine having 2 isothermal and 2 constant volume processes.

It runs on reversible processes, which yields maximum work output for given heat input. The Carnot efficiency is valid for reversible processes. These processes cannot be achieved in real cycles of power plants. The Carnot efficiency dictates that higher efficiencies can be attained by increasing the temperature of the steam.

For example, if a heat engine loses energy overcoming friction, it doesn't have a reversible process, because it doesn't end up in the same state when the process Carnot Cycle · The Carnot efficiency only depends on the highest and lowest temperature. · If we want to increase the Carnot efficiency, we can increase the highest One of the factors determining efficiency is the addition of the working fluid in the cycle and its removal. The Carnot cycle reaches maximum efficiency because all Efficiency of ideal gas Carnot cycle.

Carnot cycle is a reversible cycle and hence it as an ideal cycle, where each process of cycle will be reversible process and Carnot cycle will have the highest efficiency and hence it is also termed as highest efficient heat engine. De Franse wiskundige Sadi Carnot (1796-1832) ontwikkelde dit model om een bovengrens voor het rendement te berekenen van de omzetting van thermische energie in mechanische arbeid. Het carnotproces bestaat uit een kringloop met twee reversibele adiabatisch fasen ( isentropische processen ) en twee isotherme fasen.
