C$.$ A rectangular open channel $5m$ wide carrying a flow of $8m\frac{3}{s}.$ Slope of the channel bed is $0\mathrm{.}00652.$ Hydraulic jump occurs in the downstream part of a channel and produced a sequent depth of $2\mathrm{.}5m,$ use $n=0\mathrm{.}015.$

$(6)$ Determine the depth before the jump in $m$

$(7)$ What is the loss of energy in the jump in $m?$

$(8)$ What is the length of apron in $m?$

$(9)$ What is the Power Loss in Hp

$(10)$ Calculate the Subcritical Depth in $m$
