  2. Viscosity - Wikipedia

    en.wikipedia.org/wiki/Viscosity

    Viscosity is a measure of a fluid's rate-dependent 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]

  3. Temperature dependence of viscosity - Wikipedia

    en.wikipedia.org/wiki/Temperature_dependence_of...

    A simple and widespread empirical correlation for liquid viscosity is a two-parameter exponential: = / This equation was first proposed in 1913, and is commonly known as the Andrade equation (named after British physicist Edward Andrade). It accurately describes many liquids over a range of temperatures.

  4. 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.

  5. Viscosity models for mixtures - Wikipedia

    en.wikipedia.org/wiki/Viscosity_models_for_mixtures

    The effect of a changing composition of e.g. the liquid phase is related to the scaling factors for viscosity, temperature and pressure, and that is the corresponding state principle. The reference viscosity correlation of Pedersen et al. (1987) [18] is

  6. Stokes' law - Wikipedia

    en.wikipedia.org/wiki/Stokes'_law

    If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube. Electronic sensing can be used for opaque fluids. Knowing the terminal velocity, the size and density of the sphere, and the density of the liquid, Stokes' law can be used to calculate the viscosity of the fluid. A ...

  7. Shear thinning - Wikipedia

    Kaye effect – Property of complex liquids; Time-dependent viscosity; Rheopecty: The longer the fluid is subjected to a shear strain, the higher the viscosity. Time-dependent shear thickening behavior. Thixotropy: The longer a fluid is subjected to a shear strain, the lower its viscosity. It is a time-dependent shear thinning behavior.

    "Since dry and liquid ingredients respond differently to factors like surface tension, viscosity, and mass, each type of measuring is designed with these characteristics in mind," she says.

  9. Liquid - Wikipedia

    en.wikipedia.org/wiki/Liquid

    A non-Newtonian liquid is one where the viscosity is not independent of these factors and either thickens (increases in viscosity) or thins (decreases in viscosity) under shear. Examples of non-Newtonian liquids include ketchup, custard, or starch solutions. [37]
