  2. Volume correction factor - Wikipedia

    en.wikipedia.org/wiki/Volume_Correction_Factor

    In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. [1] It is typically a number between 0 and 2, rounded to five ...

  3. Volume of an n-ball - Wikipedia

    en.wikipedia.org/wiki/Volume_of_an_n-ball

    While the volume can be expressed as an integral over the surface areas using the coarea formula, the coarea formula contains a correction factor that accounts for how the p-norm varies from point to point. For p = 2 and p = ∞, this factor is one.

  4. End correction - Wikipedia

    en.wikipedia.org/wiki/End_correction

    In acoustics, end correction is a short distance applied or added to the actual length of a resonance pipe, in order to calculate the precise resonant frequency of the pipe. The pitch of a real tube is lower than the pitch predicted by the simple theory. A finite diameter pipe appears to be acoustically somewhat longer than its physical length.

  5. Compressibility factor - Wikipedia

    en.wikipedia.org/wiki/Compressibility_factor

    Thermodynamics. In thermodynamics, the compressibility factor (Z), also known as the compression factor or the gas deviation factor, describes the deviation of a real gas from ideal gas behaviour. It is simply defined as the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.

    Wind speed conversion factors. Meteorological data includes wind speeds which may be expressed as statute miles per hour, knots, or meters per second. Here are the conversion factors for those various expressions of wind speed: 1 m/s = 2.237 statute mile/h = 1.944 knots. 1 knot = 1.151 statute mile/h = 0.514 m/s.

  7. Allocation (oil and gas) - Wikipedia

    MF, Meter Factor, adjust to actual volume, this factor is determined by probing CTL is a volume correction factor for the effects of temperature on liquid [32] SF, Shrinkage Factor, adjusts for changes in pressure temperature and composition, for instance shrinkage of fluid occurs when pressure drops and constituents change to gas phase

  8. Van der Waals equation - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waals_equation

    The van der Waals equation, named for its originator, the Dutch physicist Johannes Diderik van der Waals, is an equation of state that extends the ideal gas law to include the non-zero size of gas molecules and the interactions between them (both of which depend on the specific substance). As a result the equation is able to model the phase ...

    The Maxwell Garnett formula, in contrast to Bruggeman formula, ceases to be correct when the inclusions become resonant. In the case of plasmon resonance, the Maxwell Garnett formula is correct only at volume fraction of the inclusions δ i < 10 − 5 {\displaystyle \delta _{i}<10^{-5}} . [ 23 ]
