Polytropic Process

Many processes can be approximated by the law:

P= Pressure,
v= Volume,
n= an index depending on the process type.

Polytropic processes are internally reversible. Some examples are vapors and perfect gases in many non-flow processes, such as: Some polytropic processes are shown in figure below:

The initial state of working fluid is shown by point 0 on the P-V diagram. The polytropic state changes are: Related topic:
