  2. List of viscosities - Wikipedia

    en.wikipedia.org/wiki/List_of_viscosities

    Consequently, if a liquid has dynamic viscosity of n centiPoise, and its density is not too different from that of water, then its kinematic viscosity is around n centiStokes. For gas, the dynamic viscosity is usually in the range of 10 to 20 microPascal-seconds, or 0.01 to 0.02 centiPoise. The density is usually on the order of 0.5 to 5 kg/m^3.

  3. Viscosity - Wikipedia

    en.wikipedia.org/wiki/Viscosity

    The proportionality factor is the dynamic viscosity of the fluid, often simply referred to as the viscosity. It is denoted by the Greek letter mu ( μ ). The dynamic viscosity has the dimensions ( m a s s / l e n g t h ) / t i m e {\displaystyle \mathrm {(mass/length)/time} } , therefore resulting in the SI units and the derived units :

  4. Poise (unit) - Wikipedia

    en.wikipedia.org/wiki/Poise_(unit)

    The poise (symbol P; / p ɔɪ z, p w ɑː z /) is the unit of dynamic viscosity (absolute viscosity) in the centimetre–gram–second system of units (CGS). [1] It is named after Jean Léonard Marie Poiseuille (see Hagen–Poiseuille equation). The centipoise (1 cP = 0.01 P) is more commonly used than the poise itself.

  6. Viscous liquid - Wikipedia

    en.wikipedia.org/wiki/Viscous_liquid

    This classification has no direct relation with the common usage of the word "fragility" to mean brittleness. Viscous flow in amorphous materials is characterised by deviations from the Arrhenius-type behaviour: the activation energy of viscosity Q changes from a high value Q H at low temperatures (in the glassy state) to a low value Q L at ...

    en.wikipedia.org/wiki/Heavy_crude_oil

    For example, the viscosity of Venezuela's Orinoco extra-heavy crude oil lies in the range 1000–5000 cP (1–5 Pa·s), while Canadian extra-heavy crude has a viscosity in the range 5000–10,000 cP (5–10 Pa·s), about the same as molasses, and higher (up to 100,000 cP or 100 Pa·s for the most viscous commercially exploitable deposits).

  8. Viscosity index - Wikipedia

    en.wikipedia.org/wiki/Viscosity_index

    The higher the VI, the more stable the viscosity remains over some temperature range. The VI was originally measured on a scale from 0 to 100; however, advancements in lubrication science have led to the development of oils with much higher VIs. [1] The viscosity of a lubricant is closely related to its ability to reduce friction in solid body ...

  9. Magma - Wikipedia

    en.wikipedia.org/wiki/Magma

    For comparison, water has a viscosity of about 1 cP (0.001 Pa⋅s). Because of this very high viscosity, felsic lavas usually erupt explosively to produce pyroclastic (fragmental) deposits. However, rhyolite lavas occasionally erupt effusively to form lava spines , lava domes or "coulees" (which are thick, short lava flows). [ 22 ]
