  • Gas constant - Wikipedia
    It is common, especially in engineering applications, to represent the specific gas constant by the symbol R In such cases, the universal gas constant is usually given a different symbol such as R to distinguish it
  • Rw function - RDocumentation
    Specific gas constant of water vapor R w = 1000 R M w = 461 52 J (k g K), where R = 8 3144621 J (m o l K) is the molar gas constant and M w = 18 01528 g m o l is the molecular weight of water vapor
  • Gases - Specific Heat and Individual Gas Constants
    The specific heat (= specific heat capacity) at constant pressure and constant volume processes, and the ratio of specific heats and individual gas constants - R - for some commonly used "ideal gases", are in the table below (approximate values at 68 oF (20 oC) and 14 7 psia (1 atm))
