Question

A jet of water having a velocity of 40 m/s strikes a curved vane, which is moving with a velocity 20 m/s. The jet makes an angle of 30o with the direction of motion of vane at inlet and leaves at an angle of 90o to the direction of motion of vane at outlet (with respect to stationary floor). Draw the velocity triangles at inlet and outlet and determine the vane angles at inlet and outlet so that the water enters and leaves the vane without shock

Answer 1

Answer:

A particle moving with a velocity equal to 0.4m/s is subjected to an acceleration of 0.15m/s2 for 2s. in a direction at the right angle to its direction of motion. The resultant velocity is
