Viscosity index - Wikipedia
The viscosity index (VI) is an arbitrary, unit-less measure of a fluid's change in viscosity relative to temperature change. It is mostly used to characterize the viscosity-temperature behavior of lubricating oils. The lower the VI, the more the viscosity is affected by changes in temperature.
Viscosity - Wikipedia
Viscosity is a measure of a fluid's dynamic resistance to a change in shape or to movement of its neighboring portions relative to one another. [1] For liquids, it corresponds to the informal concept of thickness; for example, syrup has a higher viscosity than water. [2]
Power-law fluid - Wikipedia
These fluids have a constant viscosity, μ, across all shear rates and include many of the most common fluids, such as water, most aqueous solutions, oils, corn syrup, glycerine, air and other gases. While this holds true for relatively low shear rates, at high rates most oils in reality also behave in a non-Newtonian fashion and thin.
Viscosity printing - Wikipedia
Viscosity printing is a multi-color printmaking technique that incorporates principles of relief printing and intaglio printing. It was pioneered by Stanley William Hayter. The process uses the principle of viscosity to print multiple colors of ink from a single plate, rather than relying upon multiple plates for color separation.
Melt flow index - Wikipedia
MFI is often used to determine how a polymer will process. However, MFI takes no account of the shear, shear rate or shear history and as such is not a good measure of the processing window of a polymer. It is a single-point viscosity measurement at a …

NLGI consistency number - Wikipedia
Those with a NLGI No. of 000 to 1 are used in low viscosity applications. Examples include enclosed gear drives operating at low speeds and open gearing . Grades 0, 1 and 2 are used in highly loaded gearing.
List of viscosities - Wikipedia
Kinematic viscosity is dynamic viscosity divided by fluid density. This page lists only dynamic viscosity.
