BEHAVIOR OF NEWTONIAN AND NON-NEWTONIAN FLUIDS IN PUMPING AND TRANSPORT PROCESSES

Abstract

The present study investigates the behavior of Newtonian and non-Newtonian fluids in pumping and transport processes, using a laboratory facility. The rheological behavior of the selected fluids were determined by a rotational viscometer with concentric cylinders. The effect of pressure difference on pumping of selected fluids in the laboratory circuit showed a linear decrease of effective/delivered volumetric flow rate for the Newtonian fluid, glycerin/water 80%, and a non-linear decrease for non-Newtonian fluid, Separan AP 30E, 2g/l.
