a rectangular channel with a width of 22 m is discharging 71 m3/s of water. a hydraulic jump is observed downstream of a sluice gate in the channel. between the sluice gate and the hydraulic jump, the flow depth was recorded at 60 cm. make a sketch of the situation described, and label three points on the water surface with the following numbers: (0) upstream of sluice gate, (1) downstream of sluice gate but before jump, and (2) downstream of jump. include a sketch of the energy grade line from point (0) to point (2). note: the sketch does not need to be to scale, but the relative changes in water surface elevation and egl between the three points should be evident in the sketch. derived from the conservation of mass and energy, the following equation provides an estimate for unit width discharge under a sluice gate:
