Viscosity, or a fluid’s resistance to flow, is independent of the rate of shear or shear stress, at a given temperature, for Newtonian fluids. Non-Newtonian fluids such as polymer solutions often ...

Measurement of viscosity is a subject covered by various global standards, aiming to establish a shared comprehension of testing methods and quality parameters between sellers and purchasers. The ...

Traditional methods for measuring IV of hygroscopic polymers involve dissolving the polymer in halogenated solvents such as chlorinated phenols and comparing the flow time of the solution with that of ...

A recent study used various gas oils and blends with residual heavy oils in order to evaluate the predictability of four different correlations. The gas oils differed substantially in their ...
