The shear viscosity measurements were performed for a liquid immiscible binary system Ga-Pb in a temperature-concentration range of the limited solubility using an oscillating-cup viscometer. Falling back on the results obtained and on the equation of dynamic viscosity which follows from the dynamic theory of critical phenomena the effective exponent of temperature dependence of viscosity was calculated.
