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
T1 = Temperature of heat source
T2 = Temperature of receiver
