  2. Volume (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Volume_(thermodynamics)

    Specific volume is the volume occupied by a unit of mass of a material. [1] In many cases, the specific volume is a useful quantity to determine because, as an intensive property, it can be used to determine the complete state of a system in conjunction with another independent intensive variable. The specific volume also allows systems to be ...

  3. Molar volume - Wikipedia

    en.wikipedia.org/wiki/Molar_volume

    The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas: = = Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K ...

    The van der Waals equation of state may be written as (+) =where is the absolute temperature, is the pressure, is the molar volume and is the universal gas constant.Note that = /, where is the volume, and = /, where is the number of moles, is the number of particles, and is the Avogadro constant.

  6. Specific volume - Wikipedia

    en.wikipedia.org/wiki/Specific_volume

    For a substance X with a specific volume of 0.657 cm 3 /g and a substance Y with a specific volume 0.374 cm 3 /g, the density of each substance can be found by taking the inverse of the specific volume; therefore, substance X has a density of 1.522 g/cm 3 and substance Y has a density of 2.673 g/cm 3. With this information, the specific ...

  7. Volume fraction - Wikipedia

    en.wikipedia.org/wiki/Volume_fraction

    It is the same concept as volume percent (vol%) except that the latter is expressed with a denominator of 100, e.g., 18%. The volume fraction coincides with the volume concentration in ideal solutions where the volumes of the constituents are additive (the volume of the solution is equal to the sum of the volumes of its ingredients).

  8. Van der Waals equation - Wikipedia

    That is 8 times ⁠ ⁠, the volume of each particle of radius ⁠ / ⁠, but there are 2 particles which gives 4 times the volume per particle. The total excluded volume is then ⁠ = ⁠; that is, 4 times the volume of all the particles. Van der Waals and his contemporaries used an alternative, but equivalent, analysis based on the mean free ...

    Components of a petrophysical model of a water-wet reservoir rock. Due to the complex microstructure, for a water-wet rock, the following terms comprised a clastic reservoir formation: V ma = volume of matrix grains. V dcl = volme of dry clay. V cbw = volume of clay bound water. V cl = volume of wet clay (V dcl +V cbw). V cap = volume of ...
