please answer it correctly
A jet of water with a velocity of 30 m/s impinges on a series of smooth vanes, moving with a velocity of 12 m/s, at an angle of 30° to the direction of motion of vanes. The vane angle at outlet is 18°. Find i. the vane angle at inlet so that the water enters without shock ii. the absolute velocity of the water at exit, and iii. the work done on the vanes per unit weight of water per sec entering the vanes.
