Viscosity is usually measured on a bulk scale by exposing the fluid under test to shear forces. The resistance against the shear force, caused by the internal friction of the fluid, can be measured ...

High-viscosity fluids, on the other hand, behave quite differently. They flow slowly, resist deformation, and, in some cases, act more like solids than liquids, posing challenges when it comes to ...

CUMBRIA, U.K. — Venturi flow meters are used extensively in the measurement of gas and other low viscosity fluids, such as hot water, solvents and fuels, and are a proven technology due to their ease ...

Viscosity changes with temperature, and it is recommended to use calibration oils certified at the specific temperature for optimal viscometer performance. Image Credit: Paul N. Gardner Company, Inc.

* These are nominal values. For the actual kinematic viscosity of the standard, refer to the value on the label. † Special temperature @ 23 °C. For utmost calibration accuracy, it is recommended to ...

Viscosity is a key property of fluids, influencing diffusion, mobility and quite a few other features. There are many methods for measuring macroscopic viscosity, but determining microscopic viscosity ...
