Consider the flow in a wide channel over a bump, as in Fig. P10.62. One can estimate the water-depth change or transition with frictionless flow. Use continuity and the Bernoulli equation to show that is the drawdown of the water surface realistic in Fig. P10.62? Explain under what conditions the surface might rise above its upstream position y0.
