MCQ · 1 Mark
Propulsion • Compressors and Turbines • Degree of Reaction & Velocity Triangles
In a 50% reaction compressor stage, the static enthalpy rise is:
(A) Divided equally between rotor and stator
(B) Achieved 100% in the rotor
(C) Achieved 100% in the stator
(D) Zero across both components
Answer Key:
A
Step-by-Step Verified Solution
### Solution: Degree of reaction R = \Delta h_{rotor} / \Delta h_{stage} = 0.50 means equal enthalpy rise in rotor and stator. Correct: A.
