Capillary viscometer and flow cups (orifice viscometers) The working principle of these instruments is based on the determination of the time needed for a standard volume of fluid to pass through a ...

IN a recent letter 1 Mr. A. C. Merrington points out that, when a material for which the viscosity decreases greatly with increase in rate of shear is investigated in a capillary viscometer, the ...

Viscosity, or a fluid’s resistance to flow, is independent of the rate of shear or shear stress, at a given temperature, for Newtonian fluids. Non-Newtonian fluids such as polymer solutions often ...

The United States Pharmacopeia has stated that references to General Chapter <911> "Viscosity" will be changed to General Chapter <911> "Viscosity-Capillary Viscometer Methods," <912> "Rotational ...

This article discusses how using the hand-held, solvent-free SpectroVisc Q3000 Series in the field delivers accurate kinematic viscosity measurements immediately, even when compared to conventional ...

Since it is essential to determine the viscosity of a lubricant for condition monitoring, field-based users require portable viscometers for the on-site evaluation of critical equipment. At present, ...
