The Pipe Manning's N Library command allows you to store commonly used pipe types and their manning's n values. The library file is in the ...\USER folder and is available for all projects in both culvert design and sewer network design.
From the Network > Sewer Network Libraries menu in the Hydrology Module, select Pipe Manning's N Library to open the library dialog. The Type of Pipes list displays all the stored pipe types and the Manning's n list displays the corresponding manning's n values. New button creates a new pipe manning's n entry, Edit button allows you to modify the highlighted entry, and Delete button removes the highlighted pipe entry from the library. Load and SaveAs buttons allow you to load and save the library data.
