COP of Bell-Coleman Cycle for given Temperatures, Polytropic Index and Adiabatic Index Formula

What is Polytropic Index?

The Polytropic Index is a value that represents the relationship between pressure and volume during a thermodynamic process. It varies depending on the type of process, such as isothermal, adiabatic, or somewhere in between. In air refrigeration, this index helps determine the behavior of air during compression and expansion, affecting the efficiency and performance of the cycle. It is crucial in analyzing real-world processes where ideal conditions do not apply.
