Abstract :

The dynamic shear viscosity of the binary liquid mixture water â�?�? phenol was measured for different temperatures and concentrations using the glass capillary and digital viscometers. Dynamic shear viscosity anomaly was detected near the critical temperature = 67 �?°C and the critical concentration xc= 33.9% by weight of phenol. The specific heat at constant pressure was calculated using the two scale factor universality and found to be 241.9 . The critical and the background isobaric thermal expansion coefficients were determined and found to be 2.729 x10-3 �?°C�?�?�?¹ and 22.59 x10-3 �?°C�?�?�?¹ respectively. Ultrasonic attenuation data at 9, 15, 30 and 35 MHz were analyzed using the dynamic scaling theory of Ferrell and Bhattacharjee. The values of versus yield a straight line as predicted by the theory. The experimental values of for water â�?�? phenol were compared to the scaling function F(Ï�?*') and showed good agreement with the theory.
