Area: Calculations


Are pipe lengths & slopes based on the distance between the upstream/downstream structure (eg. catchbasin) walls, accounting for the length and width of the structure?

Problem ID#: 35487


Currently, the width/length of the structure is not considered and is only used in the headloss calculations. Pipe lengths & slopes are calculated based on center-to-center distance. Meaning, the pipe length & slopes are calculated based on the difference between the upstream invert and the downstream invert of the pipes.
