A circular jet of water impinges on a flat plate as shown in Figure P10.49. The water spreads out equally in all directions and at station 1, the flow is essentially uniform over the depth Y1. The jet exit velocity V is 10 m/s and the exit diameter D is 10 mm. If you are given that R = 8D, and Y1 = D/4 (a) Find the Froude number of the flow at station 1. (b) If you are given that a circular hydraulic jump forms near station 1, estimate the depth of water after the hydraulic jump using the one-dimensional hydraulic jump relationship. Under what conditions will the accuracy of this estimate improve?

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
