WebJan 6, 2024 · The issue I'm having is that pipes will not hold the part property for manning's n. The part list has the proper value but once that part is added to a network the part holds a value of 0 and can not be changed. When in the part properties dialog box the value will hold but as soon as "apply" or "ok" is pressed it resets back to 0. WebRough wall, or corrugated pipe, have relatively high “n” values which are approximately 2.5 to 3 times those of smooth wall pipe. All smooth wall pipes, such as concrete and plastic, were found to have “n” values ranging between 0.009 and 0.010, but, historically, engineers familiar with sewers have used 0.012 and 0.013.
