Question: What is a good estimate for the absolute roughness for epoxy lined carbon steel pipe?
Keywords: expoxy,coated,steel,pipe,roughness
Answer: The 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-Williamsformula, which lists a coefficient of 130-140 for cement-lined cast iron piping. You need to decide which is moreconservative for your application.
