WebThe Manning formula for smooth bore pipe running full of water may be written in form: 2 1 3 1 2 R J n V u, or 0.3950 D0.67 J 0.5 n V u for circular pipes (AS 2200) w here n – Manning roughness coefficient, dimensionless; for polyethylene pipes, the range of n is WebA = Flow Area, (ft 2) n = Manning’s Roughness Coefficient. R = Hydraulic Radius, (ft) S = Channel Slope, (ft/ft) Under the assumption of uniform flow conditions the bottom slope is the same as the slope of the energy grade line and the water surface slope. The Manning’s n is a coefficient which represents the roughness or friction applied ...
