WebA saturation dome uses the projection of a P– v –T diagram (pressure, specific volume, and temperature) onto the P– v plane. The points that create the left-hand side of the dome represent the saturated liquid states, while the points on the right-hand side represent the saturated vapor states (commonly referred to as the “dry” region). Webquality by REFPROP 9.1 (Lemmon et al. 2016). Therefore, the vapor and liquid densities are calculated as a function of charge composition, temperature, and quality. The liquid phase mass fraction changes within ±0.01 from the charged mass fraction. The above vapor and liquid densities, ρ V and ρ L, are substituted into the orthobaric densities,
