The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness":...

the apparent viscosity is constant, and equal to the Newtonian viscosity of the fluid, but for non-Newtonian fluids, the apparent viscosity depends on the...

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...

In mathematics, the viscosity solution concept was introduced in the early 1980s by Pierre-Louis Lions and Michael G. Crandall as a generalization of...

Intrinsic viscosity [ η ] {\displaystyle \left[\eta \right]} is a measure of a solute's contribution to the viscosity η {\displaystyle \eta } of a solution...

Look up viscosity in Wiktionary, the free dictionary. Viscosity (commonly perceived as "thickness", or resistance to pouring) is the measure of the resistance...

Dynamic viscosity is a material property which describes the resistance of a fluid to shearing flows. It corresponds roughly to the intuitive notion of...

inherent viscosity is the ratio of the natural logarithm of the relative viscosity of a polymer to its mass concentration. Inherent viscosity scales inversely...

Viscosity depends strongly on temperature. In liquids it usually decreases with increasing temperature, whereas, in most gases, viscosity increases with...

antiwear additives, detergents, dispersants, and, for multi-grade oils, viscosity index improvers.[citation needed] The main function of motor oil is to...
