![3.15)
An axial flow compressor stage has blade mean velocity of 200 m/s. The stage is to be
designed for a stagnation temperature rise of 20 K and an axial velocity of 150 m/s, both constant
from root to tip. The work done factor is 0.93.
Assuming 50% reaction at mean radius, calculate the stage air angles at mean radius for free
vortex design.
