A jet of water (20◦C) impinges on a turbine blade that is translating at constant velocityU= 5 m/s. The velocity of the jet relative to the fixed nozzle of 12 cm2cross section isVj= 25 m/s. The blade turns the jet so that it makes an angleθ= 150◦measured counterclockwise from the positive x-axis. Taking into account the weight of the 150 N blade, butneglecting the weight of water on the blade, calculate:

(a) the horizontal and
(b) vertical components of force required to maintain constant blade speed.
