Friction Loss Velocity Table (Schedule 40 pipe)

Velocity is a function of the cross-sectional flow area. Therefore it is constant for a given flow rate and independent of pipe length. Values may vary slightly from other published data due to rounding. Schedule refers to strength of pipe. Wall thickness of pipe varies based on dimensions of pipe as defined in ASME standard 36.10. How is roughness coefcient calculated for PVC pipe?How is roughness coefcient calculated for PVC pipe?Roughness coefcient 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.
