Q8. A single stage impulse turbine has a mean blade diameter of 1.2 m, and the peed of rotation Is 5093 rev/min. The nozzle angle is 17 degrees to the plane of rotation and the steam leaves the nozzles at 900 mis. The blade velocity coefficient is 0. 91 and there is no axial thrust.

The steam mass flow rate is 0.05 kg/s. Calculate EACH of the following:

(a) the velocity of the blades;

(b) the blade inlet angle;

(c) the blade outlet angle;

(d) the power output.
