1. The ratio of indicated thermal efficiency to the air standard efficiency is called relative efficiency.
2. Nozzle efficiency: ratio of cumulative entholpy drop to the isentropic entholpy drop.
3. Mechanical efficiency of engine: the ratio of IP to BP.
4. Hydraulic efficiency: the ratio of runner power to the available power at the jet.
5. Compression ratio: the ratio between clearance volume and the swept volume.
