Good Morning

I am new to the forum and I am looking for some help, I am trying to find the absoulte roughness values for copper nickel 90/10, 70/30 and titanium using the colebrook equation. I have been able to locate absolute roughness values for steel and copper but cant seem to find the values for the copper alloys and titanium. Any help would be much appreciated

Thanks

Hi,

I have found a value of 0.05 mm for Titanium and Cu-Ni.

See section 6.1 of the following standard: http://www.standard....134/P-001e5.pdf

Norsok standard recommends the same value to be used for CS, Stainless Steels, Cu-Ni, and Titanium. It is equal to 0.050mm for new piping.

See page 11: http://www.standard....134/P-001e5.pdf
