Outside diameter $=350mm$

Wat thickess $=10\mathrm{.}4mm$

$Q=0\mathrm{.}056609$ m$3/$s

Manning $n=0\mathrm{.}012$

Circular pipe flowing more than haif full. Flowing a $75\%$ full.

Calculate the following $($detaled calculation$)$:

Water depth

Wetted perimeter

Hydraulic radius

Slope

Velocity $(\frac{m}{s})$

Provide an overview as to whether the diameter is sumbient to provide self$-$cleansing velocity and slope.
