Required Information

Water discharging into a $9-$m$-$wide rectangular horizontal channel from a sluice gate is observed to have undergone a hydraulic Jump. The flow depth and speed before the Jump are $1\mathrm{.}2$ m and $\backslash (12\mathrm{.}50\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ),$ respectively. Take the density of water to be $\backslash (1000\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash ).$

Determine the mechanical energy dissipated by the hydraulic Jump.

The mechanical energy dissipated by the hydraulic jump is
