Answer to Question #232177 in Mechanical Engineering for Pavan

Question

Steam issues from the nozzle of a single-impulse turbine at

800 m/sec on to blades moving at 300 m/sec. The blade tip angles

at inlet and outlet are 36º each. The steam is to enter the blades

without shock and the flow over the blades is frictionless.

Determine—

(a) the angle at which the nozzles are inclined to the motion of the

blades;

(b) diagram efficiency.

Answer 1

following is the angle at which the nozzles are inclined to the motion of the

blades and diagram efficiency.
