What Is A Good Estimate For The Absolute Roughness For Epoxy Lined Carbon Steel Pipe? |
|
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-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. The specific roughness for welded, seamless steel is .0002 ft. PVC has a specific roughness of 0.000005 ft.
