Abstract: The essential frame work of manufacturing material is composed of scientific and practical interrelationship. It plays the role among the structure, structural properties and performance of all classes of materials that are potentially useful to the society. Even after manufacturing the materials further it is necessary to study the physical and chemical properties of those materials. One of such properties can be studied by exposing the liquid or solid materials to ultrasonic vibrations .In the liquid binary system chosen for this study is toluene with benzene, hexane, heptane and cyclohexane at temperature i.e. 293.15K. The experimental value of ultrasonic velocity and density of binary mixtures are taken from the work of P.S.Nikam etal’ and the sample chosen is mainly due to the availability of the experimental data. The various acoustical parameters like ultrasonic velocity, percentage deviation, excess impedance, and excess velocity are calculated and obtained results are suitably interpreted. The ternary system chosen for this study are cyclohexane plus toluene plus 2-propanol, studied at 293.15K.The experimental value of ultrasonic velocity and density for this mixture has been taken from the work of G. Arul etal. The values of sound velocity have been evaluated theoretically using three different methods namely Nomoto, Van-deal and CFT. For both binary and ternary mixtures, the observed result shows that the Nomoto method seems to give good results for the evaluation of acoustical parameters compared to collision factor theory (CFT) and Van-deal’s method.

Keywords: Binary system, Nomoto method, CFT method, Van-deal’s Method.
