Question:medium

The degree of reaction of an axial compressor stage is defined as the ratio of

Show Hint

The degree of reaction is \[ \boxed{ R = \frac{\Delta h_{\text{rotor}}} {\Delta h_{\text{stage}}} } \] and indicates how the pressure rise is shared between the rotor and stator.

Updated On: Jul 14, 2026

Rotor work to total work
Static pressure rise in rotor to total static pressure rise of the stage
Stator work to rotor work
Total pressure rise to kinetic energy rise

Show Solution

The Correct Option is B
