N

$($a$)$ An open channel carries water down a slope. It has a trapezoidal section profile with dimensions as shown below $($water depth is $0\mathrm{.}8$ m $).$ The slope of $t$

Using the D'Arcy$-$Weisbach method and a Friction factor, $"f"$ as $0\mathrm{.}0367,$ calculate the:

I. Area of flow

II$.$ Wetted Perimeter

III. Equivalent diameter

IV$.$ Flow velocity

V$.$ Volumetric$)$ flow rate.
