I am trying to predict pressure drop in a pipeline with a range of different materials.
I have used a surface profilometer to measure the surface roughness of the different materials and I have values for various surface roughness variables - Ra Rz Rmax Rq Rm S Sm R3z Wt and a range of other...
Hi,
I am struggling with the same issue as original poster WouterWouter,
I have used a surface profilometer to measure the roughness of a range of materials, but now have no idea which measurable to use (I know Ra Rz Rmax Rq Rm S Sm R3z Wt and a bunch of other variables - but no idea which...
