Computation of acoustic nonlinearity parameter for binary and ternary liquid mixture
Keywords:
Nonlinearity parameter, Sound speed, Thermal expansion coefficient, Heat capacityAbstract
Acoustic nonlinearity parameter, B/A, of six binary systems diethyl carbonate + methanol, + ethanol, + 1-propanol, + 1- butanol, + 2-butanol, + 1-pentanol has been computed at four temperatures (293.15, 298.15, 303.15 and 313.15) K using Tong-Dong thermodynamic method, Hartmann method and Ballou empirical rule. These approaches were further extended to one ternary system: ethyl acetate + n-heptane + acetone at 298.15 K. The experimental input data were taken from literature. A comparative study of the B/A values, obtained from three different methods, is presented.
