Friction Factor of Stainless Tube

Friction Factor of Stainless Tube

Friction Factor of Stainless Tube

(OP)
I base most of my fluids system designs from Camerons Hydraulic and Crane Paper #410, neither of them list any data for friction factors in stainless (304,316L) tube. Does anyone have a reference for this info, or gathered any empirical data themselves? I'm mainly interested in numbers for polished ID tube, but info. for bright annealed would be great also.

Thanks in adavance,

RE: Friction Factor of Stainless Tube

Crane Flow of Fluids Manual gives absolute roughness for drawn tube as 0.000005 inches. Hope that healps

RE: Friction Factor of Stainless Tube

Be careful not to design too close. A roughness of .000005 in. would not give a significantly different answer than using smooth pipe.. As a worst case, consider a higher value to account for aging, deterioration of the surface, debris, jointing method, etc.
