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 ...

Gravimetric Capillary is the most common technique used to measure kinematic viscosity. It is temperature controlled, usually 40 ºC for single grade oils, and both 40 and 100 ºC for multi-grade oils.
