METHOD AND APPARATUS FOR THE DETERMINATION OF VISCOSITY

摘要

A method for measuring the viscosity of liquids including homogeniously mixed suspensions of known temperatures which comprises rapidly adjusting the temperature of the said liquid, stirring said liquid by rotating a stirring means within said liquid at a measured speed and measuring the power consumed by rotating said stirring means at said speed. The invention also includes within its ambit apparatus for performing the method which comprises a vessel, a heat transfer means adapted to accomodate said vessel and capable of rapidly adjusting the temperature of its contents a stirring means adapted to be positioned within said vessel, a motor suitable to drive said stirring means, a speed controller for controlling the speed of the stirring means and power consumption measurement means for measuring the power consumption of the motor at any given time.
