The height of water in a vessel is h. The vessel wall of width b is at an angle `theta` to the vertical. The net force exerted by the water on the wall is

A stream of water of density rho , cross sectional area A, and speed u strikes a wall that is perpendicular to the direction of the stream, as shown in the figure below. The water then flows sideways across the wall. The force exerted by the stream on the wall is
