Webbetween 150 and 160. Roughness coefficient is based on the material of the pipe. For PVC pipe, the standard C value is 150. 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. http://www.cecalc.com/References/Design%20Coefficient%20Tables.pdf
