A waterslide is built with bed slope Sb $=0\mathrm{.}02($dimensionless$)$ and width $1$ m$.$ It is flowing at $$normal flow$$ conditions with a smooth bed $($manning$$s roughness n $=0\mathrm{.}01)($dimensionless$).$ The flow is much wider than the depth, so you can approximate the hydraulic radius Rh and depth d to be equal.

Given depth d $=0\mathrm{.}01$ m$,$ calculate the normal$-$flow discharge $($Q$\backslash$
