Problem 2: Ajet of water moving at 20 m/s impinges on a symmetrical curved vane shaped to deflect the jet through 120° (that is the vane angles e and are each equal to 30°). If the vane is moving at 5 m/s, find the angle of the jet so that there is no shock at inlet. Also determine the absolute velocity of exist in magnitude and direction, and the work done.

Problem 2: A jet of water moving at 20 m/s impinges on a symmetrical curved
vane shaped to deflect the jet through 120° (that is the vane angles e and are each
equal to 30°). If the vane is moving at 5 m/s, find the angle of the jet so that there is
no shock at inlet. Also determine the absolute velocity of exist in magnitude and
direction, and the work done.
