The Reynolds number—friction factor law for smooth tubes. The equations at hand can be used to derive an important relation between and / for turbulent flow in smooth round pipes. This equation is derived by appropriate substitutions into Eq. (5.32). From the defining equation of y [Eq. (5.34)] and from the definition ofH [Eq. (5.24)]... [Pg.96]

In turbulent flow of time-independent fluids the Reynolds number at which turbulent flow occurs varies with the flow properties of the non-Newtonian fluid. Dodge and Metzner (D2) in a comprehensive study derived a theoretical equation for turbulent flow of non-Newtonian fluids through smooth round tubes. The final equation is plotted in Fig. 3.5-3, where the Fanning friction factor is plotted versus the generalized Reynolds... [Pg.159]
