Abstract

There is always a range or distribution m relaxation times rather than a single value This range in acoustic (or ultrasonic) relaxation times can be understood using the concept of the bulk viscosity coefficient of a liquid, acoustic Cole-Cole plots and a distribution parameter, the ultrasonic relaxation time is found to be a function of ultrasonic velocity, absorption and the distribution parameter A suitable expression is obtained for the relaxation time which is evaluated at various frequencies for various values of the distribution parameter, These variations are tabulated and discussed
