Q$6$: Design an inverted syphon to pass $4\mathrm{.}8m\frac{3}{sec}$ under a main road with $0\mathrm{.}25m$ head loss, $($the figure bellow shows the site dimensions$).$ The canal velocity is $0\mathrm{.}98\frac{m}{sec},$ try a square box section $(dxd)$ with $22\mathrm{.}5$ elbows at each end with safety screens, $n=0\mathrm{.}013,K_1=0\mathrm{.}2,K_2=0\mathrm{.}3,K_{sc}=0\mathrm{.}2$ and $K_{\text{e}\text{l}\text{b}\text{o}\text{w}}=0\mathrm{.}05$ and side slope of the canal is $1V$:$1\mathrm{.}5H.$
