  2. Compressibility factor - Wikipedia

    en.wikipedia.org/wiki/Compressibility_factor

    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 .

  3. Compressibility - Wikipedia

    en.wikipedia.org/wiki/Compressibility

    The compressibility factor is defined as = where p is the pressure of the gas, T is its temperature, and is its molar volume, all measured independently of one another. In the case of an ideal gas, the compressibility factor Z is equal to unity, and the familiar ideal gas law is recovered:

  4. Reduced properties - Wikipedia

    en.wikipedia.org/wiki/Reduced_properties

    These dimensionless thermodynamic coordinates, taken together with a substance's compressibility factor, provide the basis for the simplest form of the theorem of corresponding states. [1] Reduced properties are also used to define the Peng–Robinson equation of state, a model designed to provide reasonable accuracy near the critical point. [2]

    One example of standard conditions for the calculation of SCCM is = 0 °C (273.15 K) [1] and = 1.01 bar (14.72 psia) and a unity compressibility factor = 1 (i.e., an ideal gas is used for the definition of SCCM). [2] This example is for the semi-conductor-manufacturing industry.

  6. Non ideal compressible fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Non_ideal_compressible...

    The compressibility factor is a dimensionless quantity which is equal to 1 for ideal gases and deviates from unity for increasing levels of non-ideality. [ 9 ] Several non-ideal models exist, from the simplest cubic equations of state (such as the Van der Waals [ 4 ] [ 10 ] and the Peng-Robinson [ 11 ] models) up to complex multi-parameter ones ...

  8. Standard cubic feet per minute - Wikipedia

    en.wikipedia.org/wiki/Standard_cubic_feet_per_minute

    Actual cubic foot per minute (ACFM) is the volume of gas flowing anywhere in a system, taking into account its temperature and pressure. If the system were moving a gas at exactly the "standard" condition, then ACFM would equal SCFM. This usually is not the case as the most important change between these two definitions is the pressure.

    The lingering effects of a high pressure system will conspire with an approaching storm from the Midwest to make a mess across much of the East. East's wintry mix could make travel dicey. And yes ...
