WHEN a capillary-tube viscometer is used for determining the apparent viscosity of a suspension of discrete, solid particles in a liquid, it is found that the measured viscosity varies with the bore ...

Traditional viscometers rely on capillary flow, and falling balls are simple and effective means for measuring fluid viscosity over a large range. However, their low measurement throughput and lack of ...

When a force or stress is applied to a fluid, it flows, resulting in internal friction that resists the flow. Therefore, viscosity is defined as the internal friction of a fluid, or in other words, ...

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 ...

Online viscometers measure the internal viscosity of polymers, proteins, and peptides that are coupled with GPC to characterize essential physico-chemical properties, such as the distribution of molar ...

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 ...
