A nozzle discharges a stream of water of cross-sectional area A with a velocity vA. The stream is deected by a single blade (think of one blade in a turbine) which moves to the right with a constant velocity V . Assuming that the water moves along the blade at a constant speed, determine
(a) the components of the force F exerted by theblade on the stream,
(b) the velocity V for which the maximum power is developed.
