  2. Dew point - Wikipedia

    en.wikipedia.org/wiki/Dew_point

    The dew point temperature equals the air temperature when the air is saturated with water; in all other cases the dew point will be less than the air temperature. [ 6 ] : 129 In technical terms, the dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same ...

  4. Psychrometrics - Wikipedia

    en.wikipedia.org/wiki/Psychrometrics

    Dew point temperature (DPT) is the temperature at which a moist air sample at the same pressure would reach water vapor "saturation." At this point further removal of heat would result in water vapor condensing into liquid water fog or, if below freezing point, solid hoarfrost. The dew point temperature is measured easily and provides useful ...

  5. Zeotropic mixture - Wikipedia

    en.wikipedia.org/wiki/Zeotropic_mixture

    In mixtures of substances, the bubble point is the saturated liquid temperature, whereas the saturated vapor temperature is called the dew point. Because the bubble and dew lines of a zeotropic mixture's temperature-composition diagram do not intersect, a zeotropic mixture in its liquid phase has a different fraction of a component than the gas ...

  6. Bubble point - Wikipedia

    en.wikipedia.org/wiki/Bubble_point

    In thermodynamics, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is formed when heating a liquid consisting of two or more components. [ 1 ] [ 2 ] Given that vapor will probably have a different composition than the liquid, the bubble point (along with the dew point ) at different compositions are ...

  7. Potential temperature - Wikipedia

    en.wikipedia.org/wiki/Potential_temperature

    The concept of potential temperature applies to any stratified fluid. It is most frequently used in the atmospheric sciences and oceanography. [2] The reason that it is used in both fields is that changes in pressure can result in warmer fluid residing under colder fluid – examples being dropping air temperature with altitude and increasing water temperature with depth in very deep ocean ...

  8. Hydrocarbon dew point - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon_dew_point

    In the United States, the hydrocarbon dew point of processed, pipelined natural gas is related to and characterized by the term GPM which is the gallons of liquefiable hydrocarbons contained in 1,000 cubic feet (28 m 3) of natural gas at a stated temperature and pressure.

    On the left-hand vertical axis, locate and mark the point containing the pressure 100 psia. On the right-hand vertical axis, locate and mark the point containing the temperature 60°F. Connect the points with a straight line. Note where the line crosses the methane axis. Read this K-value off the chart (approximately 21.3).
