Theoretical evaluation of sound velocity, Viscosity in binary liquid system

N. SIDDHARTHAN and S. JAYAKUMAR

Ultrasonic velocity, density and viscosity have been measured using the standard techniques in the binary mixtures of m-cresol with carbon tetrachloride. The study of ultrasonic waves through the solution is used for knowing the nature and strength of the intermolecular forces and their interactions in pure liquids and their mixtures. The theoretical ultrasonic velocity in binary mixtures computed using theoretical models of liquid mixtures such as Nomoto’s relation, Ideal mixture relation, Impedance relation, Rao’s specific velocity relation, Junjie’s relation and Danusso model. The validity of the theories was interpreted in terms of average percentage error (APE). Further, the theoretical values of viscosity for the binary mixtures were calculated using different empirical relations and theories. The relative merits of these relations were discussed.
