Determine the velocity distribution corresponding to fully developed (Hagen–Poiseuille) flow through the annular space formed between two concentric tubes. Let ri and ro be the inner and outer radii, respectively. Show that the inner wall shear stress Ï„w,ri differs from the value along the outer wall, Ï„w,ro . Calculate the friction factor for this flow by using instead of Ï„w in eq. (3.24) the average Ï„w value defined based on a force balance of type (3.23): Â
