  5. Kelvin - Wikipedia

    en.wikipedia.org/wiki/Kelvin

    The kelvin (K) is now fixed in terms of the Boltzmann constant (k B) and the joule. The joule is not shown because it is a derived unit defined by the metre (m), second (s), and kilogram (kg). Those SI base units are themselves defined by the universal constants of the speed of light ( c ), the caesium-133 hyperfine transition frequency ( Δ ν ...

    The K factor or characterization factor is defined from Rankine boiling temperature °R=1.8Tb[k] and relative to water density ρ at 60°F: . K(UOP) = / The K factor is a systematic way of classifying a crude oil according to its paraffinic, naphthenic, intermediate or aromatic nature. 12.5 or higher indicate a crude oil of predominantly paraffinic constituents, while 10 or lower indicate a ...

    For example, to find the K value of methane at 100 psia and 60 °F. 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.

  9. Rankine scale - Wikipedia

    en.wikipedia.org/wiki/Rankine_scale

    The Rankine scale is used in engineering systems where heat computations are done using degrees Fahrenheit. [3] The symbol for degrees Rankine is °R [2] (or °Ra if necessary to distinguish it from the Rømer and Réaumur scales). By analogy with the SI unit kelvin, some authors term the unit Rankine, omitting the degree symbol. [4] [5]
