A jet of water moving with a velocity of 20 m/s impinges on a curved vane, which is moving with a velocity of 10 m/s. The jet makes an angle of 20° with the direction of motion of vane at inlet and leaves at angle of 130° to the direction of motion of vane at outlet. Determine: (i) The angles of curved vane tips so that water enters and leaves without shock; (ii) The work done per N of water entering the vane

i need the answer quickly

A jet of water moving with a velocity of 20 m/s
impinges on a curved vane, which is moving with
a velocity of 10 m/s. The jet makes an angle of
20° with the direction of motion of vane at inlet
and leaves at angle of 130° to the direction of
motion of vane at outlet. Determine:
(i) The angles of curved vane tips so that water
enters and leaves without shock;
(ii) The work done per N of water entering
the vane.
[Ans. (i) 0 = 37.87°; ø = 6.56°;
(ii) 20.24 Nm/s or W]
