Consider a partially$-$filled concrete culvert $(n=0\mathrm{.}14)$ with radius of $0\mathrm{.}85$ meters and $=115$ degrees.

Assume steady uniform open channel flow with slope of $0\mathrm{.}003.$ Determine the hydraulic radius $($m$)$ and

the volumetric flow rate $(\frac{m^3}{s})$ of the water passing through the culvert.

Type your final answers in the tex wox below.
