Water flows in a $1\mathrm{.}7$ m wide rectangular channel. If the vertical depth is $1\mathrm{.}2$ m and maxu is

$1\mathrm{.}9$ m$/$s$,$ find the discharge in the channel. The angle

$\backslash$theta is $25$o $.[10]$

Hint: Velocity and the area must be normal. Find h for the vertical depth given
