QUESTION $2(25)$

Through water diversion from the Mooi River, a rectangular prismatic canal of

dimensions $x(m)$ depth and $Y(m)$ width such that satisfy the following condition.

$\frac{1}{x+Y}=\frac{1}{12}$

The canal is in concrete $-$finished and is intended to service a small community. The

discharge in the canal is assumed to be $9000$lite$\frac{r}{s}.$ Calculate total energy, energy

grade line, hydraulic grade line at the start of the diversion point if its elevation is $1350$

$m$ and the depth is a third of the width.
