For the triangular channel shown in the figure below determine the normal depth, if the flow rate Q$=5$cfs$,$ the slope s$=[$table $1],$ and Manning$$s roughness coefficient is n$=0\mathrm{.}015.$ Determine whether the normal flow is super or sub$-$critical. The side slope of the channel is in degrees. B$=0\mathrm{.}8,$ $=20,$ s$=0\mathrm{.}002$ For the triangular channel shown in the figure below determine the normal depth, if the flow rate $\backslash (\backslash$mathrm$\{$Q$\}=5\backslash$mathrm$\{$cfs$\}\backslash ),$ the slope $\backslash (\backslash$mathrm$\{$s$\}=[\backslash )$ table $1],$ and the Manning's roughness coefficient is $\backslash (\backslash$mathrm$\{$n$\}=0\mathrm{.}015\backslash ).$ Determine whether the normal flow is super or sub$-$critical. The side slope of the channel is provided in Table $1$ in degrees.
