Question: axial flow compressor stage is being designed for a 5 0 Hz industrial gas turbine, with a mean blade radius of 1 . 3 m

axial flow compressor stage is being designed for a 50 Hz industrial gas turbine, with a mean blade radius of 1.3 m. Initial calculations suggest that 120 m/s would be an appropriate value for the axial velocity of the air, and that the absolute velocity vector should be oriented at 40 degrees to the whirl direction at entry to the rotor. Basing your calculations on the mean radius, determine:a. the work input per stage
