Question:medium

Stage efficiency of a single-stage axial compressor is defined as

Show Hint

For an axial compressor, \[ \boxed{ \eta_s = \frac{\Delta h_{\text{isentropic}}} {\Delta h_{\text{actual}}}. } \] Higher stage efficiency means less actual work is required for the same pressure rise.

Ratio of actual work input to isentropic enthalpy rise
Ratio of isentropic enthalpy rise to actual work input
Ratio of rotor speed to stator speed
Ratio of inlet temperature to exit temperature
