• ### List of viscosities

Viscosity is a material property which describes the resistance of a fluid to shearing flows. It corresponds roughly to the intuitive notion of a fluid's 'thickness'. For instance, honey has a much higher viscosity than water. Viscosity is measured using a viscometer. Measured values span several orders of magnitude. Of all fluids, gases have the lowest viscosities, and thick liquids have the highest.

• ### Temperature dependence of viscosity

Viscosity depends strongly on temperature. In liquids it usually decreases with increasing temperature, whereas in gases viscosity increases with increasing temperature. This article discusses several models of this dependence, ranging from rigorous first principles calculations for monatomic gases, to empirical correlations for liquids.
Understanding the temperature dependence of viscosity is important in many applications, for instance engineering lubricants that perform well under varying temperature condition

OverviewMolecular originsEtymologyDefinitionMomentum transportNewtonian and non Newtonian fluidsIn solidsMeasurement

In general, the viscosity of a system depends in detail on how the molecules constituting the system interact. There are no simple but correct expressions for the viscosity of a fluid. The simplest exact expressions are the GreenKubo relations for the linear shear viscosity or the transient time correlation function expressions derived by Evans and Morriss in 1988. Although these expressions are each exact, calculating the viscosity of a dense fluid using these relations currently requires the use of molecular dynamics computer simulations. On the other hand, much more progress can be mad
