A finite difference technique is used to calculate the velocity profile, maximum shear stress, and friction factor‐Reynolds number product for a power‐law, pseudoplastic fluid flowing through a cylindrical duct of rectangular cross section. It is assumed that the motion is rectilinear. A very simple friction factor‐Reynolds number correlation is obtained for the special case of a square duct.
