Compressor Efficiency

Compare measured compressor outlet temperature with an ideal compression process.

Starting values are examples. Enter your measurements; results update as you type.

Method & assumptions

Isentropic efficiency = inlet K × (PR^((γ−1)/γ) − 1) / measured temperature rise. Inlet/outlet temperatures and pressures must correspond to the same operating point. Values above 100% indicate heat transfer or inconsistent measurements, not a compressor performance rating.
