Q8. A single stage impulse turbine has a mean blade diameter of 580 mm, and the speed of rotation is 10560 rev/min. The nozzle angle is 18 degrees to the plane of rotation and the steam leaves the nozzles at 829 m/s. The blade velocity coefficient is 0.9 and there is no axial thrust.

For a steam mass flow rate of 0.15 kg/s, determine EACH of the following:

(a) the velocity of the blades; (2)

(b) the blade inlet angle; (6)

(c) the blade outlet angle: (4)

(d) the power output. (4)
