a
Computed with modified Olchowy–Sengers critical enhancement; the viscosity at this point for use in Eq. (5) was taken as η = 28.048 μPa s from Ref. 126 (see Section 3.3.1). Thermodynamic properties required for the enhancement term Eq. (5)–(8) are from Span and Wagner114
b
Computed with modified Olchowy–Sengers critical enhancement; the viscosity at this point for use in Eq. (5) was taken as η = 28.706 μPa s from Ref. 124. Thermodynamic properties required for the enhancement term Eq. (5)–(8) are from Span and Wagner114
c
Computed with empirical critical enhancement Eq. (10).
d
Computed without any critical enhancement term.
