What is pipe roughness coefficient?

Roughness coefficient is a value used in Manning's formula to determine energy losses of flowing water due to pipe or channel wall roughness. It is based on the material of the pipe. New steel pipe uses a C value of 140, but with use and corrosion a lower value is typically used. For HDPE pipe, a range of C values between 150 and 160 is typical.
