*The gas constant is calculated from R ϭ Ru /M, where Ru ϭ 1.9859 Btu/lbmol·R ϭ 10.732 psia·ft3
/lbmol·R is the universal gas constant and M is the
molar mass.
Source: Specific heat values are mostly obtained from the property routines prepared by The National Institute of Standards and Technology (NIST),
Gaithersburg, MD.
