The rate of steady and uniform flow in a rectangular concrete channel is measured with a full$-$width rectangular sharp crested weir. The length of the weir is $3\mathrm{.}20$ m$,$ and the head over the crest of the weir is $680$ mm$.$ Further downstream in the channel, a change in the bed slope creates a hydraulic jump.Determine the sequent depth of the hydraulic jump if the initial depth is $350$ mm$,$ and calculate the total power dissipated by the hydraulic jump.
