Toilet waste lines are often 3″ or 4″. Rh = hydraulic radius (ft, m) S = slope - or gradient - of pipe (ft/ft, m/m) Hydraulic radius can be expressed as. Diameter of pipe (m, ft) Slope (m/m, ft/ft) n (1.0 for SI units, 1.486 for Imperial units) Manning coefficient of roughness. Such decreased slopes will only be considered where the depth of flow will be at least 0.3 of the pipe diameter for design average flow. If the gradient is steeper than 1 in 40, the liquid may run faster than the solids in the sloping foul water pipe thus leaving the solids stranded, which could then block the pipe. Slope or gradient of a line describes the direction and the steepness of a line. Pressed Air Pressure Loss In Pipe Lines Calculator With Metric And Imperial Units.
