Abstract :

The dynamic shear viscosity of a binary liquid mixture phenol â�?�? water has been measured at different temperatures and concentrations. The critical temperature Tc and critical concentration are found to be 67.0�?ºC and 33.90% by weight of phenol respectively, the critical density ρc is measured to be 0.8952 gm/cm3.The critical and background amplitudes of specific heat at constant pressure are calculated to be 78.117 J/kg.K and 85.292 J/kg.K respectively. The pressure derivative of the critical temperature along the critical line Tc is calculated to be 9.722 �?�?10-6 K/Pa. The dynamic shear viscosity of binary liquid mixture phenol â�?�? cyclohexane has been measured at different temperatures and concentrations. The critical temperature Tc and critical concentration are found to be 17.0 �?ºC and 2.70% by weight of phenol respectively. The critical density ρc is measured to be 0.7627 gm/cm3.The critical and background amplitudes of isobaric thermal expansion coefficient �?±pc and �?±pb are calculated to be 4�?�?10-6 K-1, 6�?�?10-4 K-1 respectively. The pressure derivative of the critical temperature xc for the binary is calculated to be 1.083 �?�?10-8 K/Pa. The universal quantityR+�?¾ of both binary liquid critical mixtures phenol â�?�? water and phenol â�?�? cyclohexane are calculated to be 0.2716and 0.2699 respectively. The values are in a good agreement with the theoretical value of R+�?¶. The two binary liquid critical mixtures belong to the class of universality "Two â�?�? Scale â�?�? Factor Universality".
