Outside diameter $=250mm$

Wall thickness $=7,4mm$

$Q=0\mathrm{.}042829m^3/$s

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

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

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

Water depth

Wetted perimeter

Hycradic radius

Slope

Velocity $(m/$s$)$

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