Pressure of water obtained with the Benedict–Webb–Rubin (BWR) equation (P-BWR) as a function of pressure computed in our simulations (P-DP). We show values for several T and ρ conditions. The contributions from virial terms (first, second, third, and sixth) to P-BWR are also shown. We plot a dashed line, y = x as a guide to the eye, showing that P-BWR and P-DP values are close to each other. The P-BWR and P-DP are obtained on a dense grid, and the parameters in the BWR model are optimized (see text).
