CARNOT CYCLE

   This cycle is of great value to heat power theory although it has not been possible to construct a practical plant on this cycle. It has high thermodynamics efficiency.
It is a standard of comparison for all other cycles. The thermal efficiency (η) of Carnot cycle is as follows:
              η = (T1 – T2)/T1
              where, T1 = Temperature of heat source
              T2 = Temperature of receiver
