In this paper a modified Benedict-Webb-Rubin (BWR) equations of state (EOS)
is proposed. A series of thermodynamic properties is applied to obtain the
constants in the equation. The final equation contains only one empirical
parameter. The validity of the equation is verified by calculating the PVT
properties of different substances in very wide density, pressure and tempe
rature range, and the results are satisfactory. (C) 2001 Elsevier Science B
