Here is the problem, i have a pipe of 2", commercial steel with absolute roughness of 0.046 mm. But the CFX needs the Rougness sand Grain in the CFX-Pre and I'm really confuse about this. I've already read some references but i still don't understand. So please, help me to find...

3.4.4 Effect of Pipe Roughness Considerable confusion exists regarding the effect of the pipe wall roughness on the value of friction factor in the turbulent flow region, though the effect is qualitatively similar to that for Newtonian fluids (Slatter, 1997; Slatter and van Sittert, 1997; Sla...
For the regions processed by the scanning velocity of 100 mm/s, the roughness ratios vary for all the laser fluences used in the experiment. The worst case is when the laser fluence used is 15 J/cm2 where the r value is 3.1689. The roughness factor plays an important role in the ...
Turbulent flow in pipesFlow tests were conducted on a total of 7 commercial stainless steel (SS) pipes of two sizes: 114.3 mm and168.3 mm O.D., and lengths of approximately 5 m, sourced from different manufacturers. The working fluid is a pipeline quality natural gas at a pressure range ...
Pipe Roughness Coefficient :4.5 10. What is absolute pipe roughness? 'Absolute Pipe Roughness' (ε) isa measure of pipe wall irregularities of commercial pipes. ... The absolute roughness has dimensions of length and is usually expressed in millimeter (mm) or feet (ft). For example, the abs...
