Question

2) A thin plate with a circular hole in it is placed on top of a vertical pipe, as shown in the figure below. Water from the pipe exits to the atmospbere through a small hole in the plate of area AD The cross-sectional area of the pipe is Ap, and Vpis the velocity of the water in the pipe. The weight of the plate steady, and igpore body forces on the flud 125 pts) (a) Write an expressionor has density ρ and specific weight γ The flow is inviscid, in the pipe. Po in terms of the variables given. A x-section view (b) Starting with a control volume that shows all relevant flows and forces, write the momentum equation that governs this problem and determine an expression for the minimum weight, W, of the plate required to prevent it from being lifted off the end of the pipe. Ignore body forces on the fluid び,-。 + 2
