When a jet of liquid escapes through the orifice of a reservoir driven only by the force of gravity, like the one in figure 3, the velocity distribution at the outlet can be approximated by u = [2g (hz)] ^ (1 // 2) diffuse h is the depth at which the center of the jet is located.  Near the hole, the jet is horizontal two-dimensional and of thickness 2L, as shown in the figure.  Obtain the general expression to calculate the total flow Q that leaves through the orifice and simplify the result in the limit L << h

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.
