HAND SOLUT$$ON$.$ Detailed flow diagram for flocculation$/$sedimentation unit in WTP

In a drinking water treatment plant, flow is distributed into $4$ tanks and then collected in a single

effluent channel as shown in the Figure. Width of each sedimentation tank is $18m.$ Effluent ports

are created by placing $0\mathrm{.}9m-$wide plates with a center to center distance of $1\mathrm{.}28m.$ Effluent ports

are submerged $(K=0\mathrm{.}8)$ and the depth of the ports are $0\mathrm{.}3m.$ The velocity at each effluent port is

$0\mathrm{.}833\frac{m}{s}.$ Effluent collection channel width is $5m.$ If the water surface elevation $($WSEL$)$ at

control point $3$ is $100\mathrm{.}000m$ and the invert depth of the effluent channel is $97\mathrm{.}000m.$ Which of the

following options correctly gives the WSEL at control point $5.$ Use at least $3$ decimals! $(n=0\mathrm{.}013)$
