The above coefficients may be used for pressure range of 0.02–2.0 bar except for water for which the pressure range is 0.01–16
bar as reported in Ref. [12]. These coefficents can generate vapor pressure near atmospheric pressure with error of less than
0.1%. There are other reported coefficients that give slightly more accurate results near the boiling point. For example, some
other reported values for A, B,and C are given here. For water: 11.6568, 3799.89, and –46.8000; for acetone: 9.7864, 2795.82,
and –43.15 or 10.11193, 2975.95, and –34.5228; for ethanol: 12.0706, 3674.49, and –46.70.
