10.18 A channel has a rectangular cross section, a width of 40 m, and a flow rate of 4000 m3 /s. The normal water depth is 20 m. The flow then encounters a 4.0-m-high dam. Find the water depth directly above the dam if the flow is critical. Assume frictionless flow. Gerhart, Philip M.; Gerhart, Andrew L.; Hochstein, John I..
