Evaluate the impact of a jet of fluid on a stationary plate.

1. A jet of water strikes a plate that is vertically positioned in front

of the jet. The density of the water is 1025kqm³ and the

velocity of the jet is 45m/s. The jet emerges from a nozzle with a

diameter 2.5cm. Find the force required to hold the plate in

position.

B. The plate is then inclined 45 degrees, what force is now

required?
