“The Hazen-Williams C-factor describes the relative smoothness of the inside surface of a pipe.” “The rougher the pipe, the more energy is required to pump water through it,” says Horn. “We recommend a C-factor of 140 for cement mortar-lined ductile iron pipe, which is the average result we got for all of the field tests we’ve done through the years.”

March 1996 PHILLIPS DRISCOPIPE Hazen-Williams Pipe Coefficient

The “C” factor is considered to be a measurement of the smoothness of the pipe wall. The formula for determining pressure drop, over a 100 foot section of pipe is ∆P100 = (452*Q1.85)/(C1.85*D4.86), where Q is the rate of flow (GPM), D is the pipe’s internal diameter (inches) and C is the Hazen-Williams smoothness pipe coefficient.

C-Factor - Shared Knowledge Safe Water

Different types of piping will have a different C-Factor, and the higher the C-Factor, the smoother the pipe. This nuer does not remain constant, because over time you will have deposits in the system and corrosion of pipes, two things that will increase your friction loss.
