The study of mass transport properties, such as density and viscosity of mixed solvent systems (both aquomixed and nonaqueous liquids), have proven to be a very useful tool in investigating specific intermolecular interactions and structural effects in condensed phases of real components. The knowledge of these properties and of some related quantities is of strategic importance for a lot of technical and scientific applications, and the availability of correlation models with temperature and chemical composition, which can be employed both for interpretative and predictive calculations, is extremely useful for chemists, physics, biologists, practising engineers and research workers devoted to material sciences.

Here, some of the most significant descriptive relationships will be summarised (together with their graphical representations), and some new concepts will be introduced to reach a better understanding about some Newtonian and pseudo-rheological complex systems. The chosen species for these studies pertain to the class of 1,2-ethanedyil-derivatives, such as 1,2-ethanediol (ED), 2-methoxyethanol (ME), 1,2-dimethoxyethane (DME), di-ethylen-glycol (DEG), 1,2-propanediol (12PD), 2-butanone (MEK), in addition to water (W) and to DMF among other solvents, in order to construct a suitable data-base.

Emphasis has been given to some aspects related to the peculiar hydrodynamic behaviour of water and to its binary and ternary mixtures.

Furthermore, some standpoints on excess mixing properties (YE) of multicomponent solvent systems are focused.
