Poiseuille flow of a fluid with variable viscosity

Abstract: The Poiseuille flow in a pipe for non-Newtonian fluid was examined. It is assumed that fluid viscosity is dependent on shear rate by power law. By solving Navier–Stokes equations we obtained velocity and volumetric flow rate solutions which summarize Poiseuille law for a Newtonian fluid.

Keywords: Poiseuille flow, non-Newtonian fluid, viscous fluid.
