  2. Darcy (unit) - Wikipedia

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

    This conversion is usually approximated as 1 μm 2. This is the reciprocal of 1.013250—the conversion factor from atmospheres to bars. [1] Specifically in the hydrology domain, permeability of soil or rock may also be defined as the flux of water under hydrostatic pressure (≈ 0.1 bar/m) at a temperature of 20 °C. In this specific setup, 1 ...

  3. Poise (unit) - Wikipedia

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

    A centipoise is one hundredth of a poise, or one millipascal-second (mPa⋅s) in SI units (1 cP = 10 −3 Pa⋅s = 1 mPa⋅s). [4] The CGS symbol for the centipoise is cP. The abbreviations cps, cp, and cPs are sometimes seen. Liquid water has a viscosity of 0.00890 P at 25 °C at a pressure of 1 atmosphere (0.00890 P = 0.890 cP = 0.890 mPa⋅s).

  4. Viscosity - Wikipedia

    en.wikipedia.org/wiki/Viscosity

    The centipoise is convenient because the viscosity of water at 20 °C is about 1 cP, and one centipoise is equal to the SI millipascal second (mPa·s). The SI unit of kinematic viscosity is square meter per second (m 2 /s), whereas the CGS unit for kinematic viscosity is the stokes (St, or cm 2 ·s −1 = 0.0001 m 2 ·s −1 ), named after Sir ...

  7. List of viscosities - Wikipedia

    en.wikipedia.org/wiki/List_of_viscosities

    For kinematic viscosity, the SI unit is m^2/s. In engineering, the unit is usually Stoke or centiStoke, with 1 Stoke = 0.0001 m^2/s, and 1 centiStoke = 0.01 Stoke. For liquid, the dynamic viscosity is usually in the range of 0.001 to 1 Pascal-second, or 1 to 1000 centiPoise. The density is usually on the order of 1000 kg/m^3, i.e. that of water.

    where is the viscosity of the liquid mixture, is the viscosity (equation) for fluid component i when flowing as a pure fluid, and is the molfraction of component i in the liquid mixture. The Grunberg-Nissan (1949) [10] mixing rule extends the Arrhenius rule to

  9. Saponification - Wikipedia

    en.wikipedia.org/wiki/Saponification

    The reaction of fatty acids with base is the other main method of saponification. In this case, the reaction involves neutralization of the carboxylic acid. The neutralization method is used to produce industrial soaps such as those derived from magnesium, the transition metals, and aluminium.
