At higher shear rates there is no significant variation and the coefficient of viscosity is almost constant over the entire range of shear rate.
As a first approximation, the following expression (Barus equation) can be used to determine the parameter, [[beta].sub.p], known as the pressure coefficient of viscosity:
In the exponential relations (15, 16) [beta] is the pressure coefficient of viscosity, P stands for the gauge pressure, [alpha] means the temperature coefficient of viscosity, and T and [T.sub.r] are tested and reference temperatures, respectively.
It was noted that the concentration coefficient of viscosity, [Psi], was a considerably negative value, as expected.
