A 50% degree-of-reaction turbine with a mean radius of 0.4 m rotates at 9000 RPM. The axial velocity through the stage remains constant at 150 m/s. The turbine nozzle deflects the flow by 70 degrees in the direction of rotor motion. Mass flow through the turbine is 10 kg/s. What are?

a) The rotor velocity, U

b) β2

c) The magnitude of c2

d) The magnitude of w2

e) α3

f) The magnitude of c3

g) The power extracted
