The "fall" of a sewer pipe is defined as the vertical distance by which one end (or one end of a section) of the pipe drops relative to the other. Contact Us; Order. Column 12 represents inflow from a storm sewer line, branch, an offsite source that flows into the trunk line being analyzed. This calc is mainly for pipes full with water at ambient temperature and under turbulent flow. This spreadsheet accomplishes a storm sewer design using the rational method. The velocity in the sewer pipe must be greater than or equal to the design minimum velocity (usually 3 ft/s). That’s a good point, thank you! The chart is in compliance with ANSI B36.10M and API 5L.

Choose from our selection of metric pipe, including pipe and pipe fittings, metal tubing for flow, and more. The above Hazen-Williams formula when converted into metric units reduces to Contact Our Experts. The Minimum Fall for Sewer Pipes is determined to ensure that the water reaches a minimum velocity when running full. Multiply the number of feet of your pipe (X) by the inches you’re planning to slope the line (Y). velocity for a pipe with an 0.013 manning's N yields minimum slopes of 0.32% for 15" dia., 0.17% for 24"dia., and 0.10%for 36"dia. A pipe that is too flat will prevent waste from flowing away.
