A jet of water is directed at a vane that could be a blade in a turbine. The water leaves the nozzle with a speed of 15 m/s and mass flow of 250 kg/s; it enters the vane tangent to its surface (in the x direction). At the point the water leaves the vane, the angle to the x direction is 120 degrees. Compute the resultant force on the vane if:
1. The vane is held constant.
2. The vane moves with a velocity of 5 m/s in the x direction.
