###### Question details

A spillway from a dam is designed as a rectangular channel 15 ft. wide. The design engineer computed that at the bottom of the spillway the depth was expected to be 1.0 ft flowing at a velocity of 35 fps. A flat flow dissipation structure (a stilling basin) is designed at the bottom of the spillway to induce a hydraulic jump (so appreciable bottom slope in the basin). You have been tasked with computing a. The Froude number at the bottom of the spillway b. The expected depth, velocity and head loss following the hydraulic jump.
