WebThe pipe outlet submergence parameter, Tw/D, was calculated by dividing the channel tailwater depth (Tw), measured relative to the pipe exit invert, by the pipe inside diameter (D). The flow area expansion term, Ap/Ach, is the ratio of the pipe and channel flow cross-sectional areas. WebhTW = velocity head in tailwater (ft. or m) ho = exit head loss (ft. or m). The outlet depth, H o, is the depth of the hydraulic grade line inside the culvert at the outlet end.
