  • Inspite of tremendous impressive developments of the molecular theory, an engineer frequently finds the need for physical properties, which have not been measured. The molal volume of a fluid at a given pressure and temperature is an equilibrium thermodynamic property. In the present work, Wassiljewa equation in conjunction with Hildebrand's relation has been applied to evaluate molal volume of the various classes of liquid mixtures (binary, ternary and quaternary). It has the advantage over the empirical relations since it can be applied to a wide variety of fluids in moderate range. Moreover, it is very simple in form and the parameters have physical significance that is easy to conceive. It was observed after extensive fitting to the Hildebrand relation that V0 for most pure fluid range between 0.3 and 0.32 times the critical volume.
