Near the downstream end of a river spillway, a hydraulicjump often forms, as illustrated in Fig. P5.123 and Video V10.11.The velocity of the channel flow is reduced abruptly across thejump. Using the conservation of mass and linear momentumprinciples, derive the following expression for h2,h2 = h12+ B(h12 )2+2V21h1gThe loss of available energy across the jump can also be determinedif energy conservation is considered. Derive the loss expressionjump loss = g(h2 h1)34h1h2
