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 ...

In the same category of capillary viscometers, tube viscometers (Figure 2C) use a horizontal tube fed by a pressurized tank to determine viscosity.2 In these instruments, the pressure is determined at ...

The most commonly used physical property for lubricants is kinematic viscosity. This article describes how using the solvent-free SpectroVisc Q3000 Series device in the field offers accurate and ...

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 ...

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 ...

Knowing the viscosity of a lubricant is critical for condition monitoring. As a result, field-based users need portable viscometers to immediately assess critical equipment while working on-site.
