Question:
An axial-flow compressor stage with hub and tip radii rh = 38 cm and rt = 61 cm is designed with the following data:
N = 6000 rpm,
ΔT0s = 19.5 K,
Cx = 137 m/s,
λ= 0.92,
Rm = 0.5.
Determine the flow angles at the hub, mean, and tip radii of both inlet and outlet of the rotor. Also calculate the degrees of reaction at both hub and tip.
