Question:medium

For an axial turbine stage, the work done per unit mass flow is directly proportional to

Show Hint

Euler's turbine equation: \[ \boxed{ W = u\left(V_{w1}-V_{w2}\right) } \] shows that turbine work depends on the change in the whirl component of velocity.

Updated On: Jul 14, 2026

Change in axial velocity
Change in whirl (tangential) velocity
Absolute inlet velocity only
Blade height only

Show Solution

The Correct Option is B
