Impact of neglecting the variations in the relative surface roughnesses of capillary tubes on the accuracy of a capillary tube model

  Existing capillary tube models rely heavily on friction factor correlations, which enable the specification of the relative surface roughness. However, measuring the surface roughnesses of capillary tubes is a time consuming task, which requires specialized equipment. In this research we have developed a friction factor correlation, which does not Read more…
