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 ...

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, ...
