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...

Volume viscosity (also called bulk viscosity, or second viscosity or, dilatational viscosity) is a material property relevant for characterizing fluid...

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

In object oriented programming, viscosity refers to the ease at which a developer can add design-preserving code to a system. If it is easier to add a...

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

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

Fuel viscosity control is a technique to control viscosity and temperature of fuel oil (FO) for efficient combustion in diesel engines of motor vessels...

not follow Newton's law of viscosity, that is, it has variable viscosity dependent on stress. In particular, the viscosity of non-Newtonian fluids can...

This equation represents apparent viscosity where apparent viscosity is the shear stress divided by shear rate. Viscosity is dependent on stress. This is...

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

Extensional viscosity (also known as elongational viscosity) is a viscosity coefficient when the applied stress is extensional stress. It is often used...

loss of viscosity and alkalis in strong concentration also tend to reduce viscosity. It is insoluble in most hydrocarbon solvents. The viscosity attained...

Relative viscosity ( η r e l {\displaystyle \eta _{rel}} ) (a synonym of "viscosity ratio") is the ratio of the viscosity of a solution ( η {\displaystyle...

Viscosity printing is a multi-color printmaking technique that incorporates principles of relief printing and intaglio printing. It was pioneered by Stanley...

In fluid dynamics, the reduced viscosity of a polymer is the ratio of the relative viscosity increment ( η i {\displaystyle \eta _{i}} ) to the mass concentration...

properties play significant roles in disease processes. Blood viscosity is determined by plasma viscosity, hematocrit (volume fraction of red blood cell, which...

High viscosity mixers are mixers designed for mixing materials with laminar mixing processes because the ingredients have such high viscosities that a...

β-glucans do become insoluble above a certain concentration. The total viscosity is determined by the level of solubility, the molecular weight, and the...
