4 B. Design Approach 1. Direct Bury Flexible pipes have been used for standard direct bury appliions since the early days of corrugated metal pipe in the 1870’s. The early uses of flexible pipe were mainly for storm drainage and culverts. As the acceptance grew

Unrealistic roughness coefficient could impair pipe capacity

More specifically, design engineers need to use an appropriate flow resistance coefficient, or Manning’s n roughness coefficient. Many jurisdictions across Canada seem to agree that a Manning’s n Value of 0.012 or 0.013 is appropriate for all smooth wall pipe.
