Carnot Cycle
Theorem:- "It states that for all engine working between same temperature limit, Reversible cycle efficiency is greater than Irreversible cycle Efficiency".
Carnot Cycle consist of two Adiabatic and two Isothermal processes.To realize Isothermal process, Piston must move at very slow rate.Where as for Adiabatic process Piston must move at very high rate and hence these two process in a cycle is not impossible.Therefore Carnot cycle is not used in practice but used for comparision of other cycles with Carnot.
