What is a good estimate for the absolute roughness for epoxy lined carbon steel pipe?
Submitted by: AdministratorThe specific roughness for welded, seamless steel is .0002 ft. PVC has a specific roughness of 0.000005 ft. You may also want to consider using the Hazen-Williams formula, which lists a coefficient of 130-140 for cement-lined cast iron piping. You need to decide which is more conservative for your application.
