Abstract

Measurements of the ultrasonic velocity and density with the viscosity are very important to find out the different basic properties of the liquid and their mixtures. These properties can be studied with simplicity and accuracy by the ultrasonic technique, therefore more preferred than the other methods. Here the measurements of Ultrasonic velocity (u) with density (r) and coefficient of viscosity (h) are carried out to find out the different ultrasonic parameters with varying composition of the binary system at three temperatures 303, 308 & 313K. The results have been discussed and graphically plotted. The determinations of excess values are so important that they provide details of the strength of the any existing interaction. Therefore the excess values of the above parameters are also evaluated and the results are shown graphically. The data confirms the existence of interaction in the binary mixture.
