A jet of water impinges on a vane tangentially and is deflected horizontally through an angle a = 60°, as shown. The vane itself is moving with absolute (i.e. with respect to a stationary observer) velocity U= 4 m/s in the same direction as the incoming fluid. The jet’s absolute velocity at inlet is V; = 22 m/s and its area A; = 0.001 m². Assume frictionless flow. Determine the magnitude and direction (angle 0) of the force F by the water on the moving vane, and the power generated by the vane. 0 vane U area A; F water jet
