[PDF] Top 20 Measurement of Viscosity for Synthetic Polymers

... Viscosity is an internal property of fluid that offers resistance to flow or it is the measure of the internal friction of a fluid. This friction becomes apparent when a layer of fluid is made to move in relation ... See full document
