4. A single-stage Impulse turbine has a diameter a of 1.5 m and runs at 3000 RPM. The nozzle angle is 20°. The speed ratio is 0.45. The ratio of relative velocity at the outlet to that at the inlet is 0.9. The outlet angle of the blade is 3 less than the inlet angle. The steam flow rate is 6 kg/s. Draw the velocity diagrams and find the following. a) Velocity of whirl [3] b) Axial thrust [3] c) Blade angles [3] d) Power developed [3] e) Stage efficiency [3]
