WebS = Slope (ft/ft) of the energy grade line, which is approximately equal to the sanitary sewer line design slope. n = Manning's Pipe Roughness Coefficient = 0.013 A Manning’s Coefficient of 0.013 shall be used for all design calculations, regardless of pipe type and diameter. WebThe friction slope, S f, is calculated by rearranging Manning’s Equation to Equation 6-24. Equation 6-24. where: S f = friction slope (ft./ft. or m/m) Q = discharge (cfs or m 3 /s) n = Manning’s roughness coefficient z = 1.486 for use with English measurements only. A = cross-sectional area of flow (sq. ft. or m 2 )
