What is Carnot Theorem?Ĭarnot’s theorem states that all heat engines between two heat reservoirs are less efficient than a Carnot heat engine operating between the same reservoirs. The efficiency of the cycle is obtained by comparing the total work W to the total heat input QIN. The real engine is expected to have valves for example: valves open at point 5 to remove exhaust gas. How do you solve a Carnot cycle? What is the equation of efficiency of engine? These temperatures are of course in degrees Kelvin, so for example the efficiency of a Carnot engine having a hot reservoir of boiling water and a cold reservoir ice cold water will be 1(273/373)=0.27, just over a quarter of the heat energy is transformed into useful work.
