HIGH SHEAR RATE VISCOSITY OF ENGINE OILS

This paper describes the development and use of a pressure capillary viscometer for operating at the temperatures and high shear rates typically experienced in operating engines. It has been used to make viscosity measurements on engine oils without significant problems at temperatures ranging from 20 to 150 degree C and shear rates up to 2 X 10**6S** - **1. Experimental results with Newtonian fluids have been found to agree extremely well with the mathematical predictions of Newtonian behavior and the Poiseuille-Hagen equation for capillary flow.
