A single stage impulse rotor has a blade ring diameter of 57.5 cm and rotates at a speed of 10,000 r.p.m. The nozzles are inclined at 20o to the direction of motion of the blades and the velocity of the issuing steam is 1,050 m/sec. Determine the inlet blade angle. Assume a friction coefficient of the blading equal to 0.85 and that the inlet and outlet angles are equal. Find also: (a) the power developed at the blades for a steam supply of 1,350 kg per hour (b) the diagram efficiency, and (c) the loss of kinetic energy due to blade friction

Q. A single stage impulse rotor has a blade ring diameter of 57.5 cm and rotates at a speed of 10,000 r.p.m. The nozzles are inclined at 20o to the direction of motion of the blades and the velocity of the issuing steam is 1,050 m/sec. Determine the inlet blade angle. Assume a friction coefficient of the blading equal to 0.85 and that the inlet and outlet angles are equal. Find also:

(a) the power developed at the blades for a steam supply of 1,350 kg per hour

(b) the diagram efficiency, and (c) the loss of kinetic energy due to blade friction
