PEREZ ONES, Osney; DIAZ RODRIGUEZ, Jorge; ZUMALACARREGUI, Lourdes  e  GOZA LEON, Osvaldo. Evaluation of physical properties of ethanolwater mixtures (II). Rev.fac.ing.univ. Antioquia [online]. 2010, n.52, pp. 62-74. ISSN 0120-6230.

In this work, models to estimate physicals properties for ethanol-water mixtures are shown for atmospheric pressure. This is achieved through a quick and simple method with a minimum of information, starting with measurable properties. Models to estimate density, dynamic viscosity, thermal conductivity, surface tension and refractive index are based on statistic methods. Obtained values are compared with different literature sources showing, satisfactory adjustments.
