A concrete$-$lined canal with an $n-$value of $0\mathrm{.}014$ is constructed on a slope of $0\mathrm{.}33\frac{m}{k}m$ and conveys $23$

$m\frac{3}{s}$ of water. The canal is trapezoidal in cross section with a bottom width of $B=6m$ and $H$:$V$ side

slopes of $1\mathrm{.}5$:$1.$ Find a$)$ the uniform flow depth and b$)$ the stream power.
