## Outlet StructureOutlet weir
Provide 90^{o}angle V-notch on both side of launders, weir loading rate14,000 gpd/ft at Q_{p}Weir length per tank
Number of launders: Convey launder width = 2.5 ft, Tank width = 25 ft,
Number of V-notch weir: At peak flow, width of V-notch = 8"
Discharge q and hydraulic head over one V-notch ^{(1)} One tank service at Q_{p}=10 mgd,
Cd=0.575
Two tanks service at Q _{p}=10 mgd, or one tank for Q_{A},_{d}=5.0 mgd
Two tanks service at Q_{A,d}=5.0 mgd
All of which fit the design standard well.
5.Dimension of launder of V-notch Figue 15. Water surface profile in the effluent launder(Dimesions don't apply).
Width of launders, b=1'; y_{1}is depth of the luanders; Space between any two launders = 2'; The flow profile in launders is parabolic curve; y_{2}= the water depth at the end of launder, Select y_{2}= 2'; n = Number of V-notch per launder/2; l = Width of tank/2; q = flowrate per V-notch; at Q_{p},
