Webwhere is the modified Reynolds number given by Equation 2-29 and (2-43) is the Hedström number. The non-Newtonian friction models outlined above do not include any effects of wall roughness. Since the laminar sub-layers tend to be thicker than non-Newtonian than for Newtonian fluids, the effect of pipe roughness is likely to be smaller.
