Apparent viscosity the ratio of shear stress to rate of shear of a non-Newtonian fluid such as lubricating grease, calculated from Poiseuilles equation and measured in poises. The apparent viscosity changes with changing rates of shear and temperature and must, therefore, be reported as the value at a given shear rate and temperature If you are interested in our products, consult now to get a more favorable price;
