A jet of water of cross-sectional area A, issuing from a stationary nozzle with a velocity V strikes a vertical plate concentrically. Develop an expression for the force required to hold the plate in place. Water flowing at the rate of 0.034 m³
/s strikes a flat plate held normal to its path. If the force exerted on the plate in the direction of incoming water jet is 720 N, calculate the diameter of the stream of water.
