Tait

Model for Density (Liquid)

ρsat/ρ = 1 - C×ln[(B + p)/(B + psat)]
B = biti, i [0, nterms,b - 1]
C = citi, i [0, nterms,c - 1]
t = (T - Tcent)/100

where ρsat = density of saturated liquid, psat = saturation vapor pressure and Tcent = a fit constant

The basis for this functional form is discussed in [31].
