A river of width b and depth h1 passes over a submerged obstacle, or “drowned weir,” in Fig. P3.80, emerging at a new flow condition (V2, h2). Neglect atmospheric pressure, and assume that the water pressure is hydrostatic at both sections 1 and 2. Derive an expression for the force exerted by the river on the obstacle in terms of V1, h, h2, b, P, and g. Neglect water friction on the river bottom.
