Show me the steps to solve d$)$ A long, rectangular open channel $3$ m wide carries a discharge of $15\frac{m^3}{s}.$ The upstream and downstream of the channel are installed with a sluice gate and a tailgate respectively, as indicated in Figure Q$2($d$).$ The channel has a bed slope of $0\mathrm{.}004,$ and the Manning's coefficient, $n,$ is $0\mathrm{.}01.$ The sluice gate is lifted, allowing water to flow under it and at a certain point in the channel, flow reaches normal depth. If a hydraulic jump takes place at this depth, solve for the subsequent depth, flow classification and the energy loss through the jump.
