rent practice in the United States. International readers are 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 Table A.3 Friction Loss Through Fittings in Equivalent Footage of Pipe. Data Courtesy IPEX

Fiberglass Reinforced Plastic Pipe

Fiberglass pipe has a smoother internal surface than steel pipe, with a Hazen-Williams roughness coefficient of 160 when new, or 150 used. Steel pipe, on the other hand, has a Hazen-Williams roughness coefficient of 120 when new, or 65 used. The far greater loss in smoothness for the steel pipe is due to scale build-up on the steel pipe.
