Viscosity Measurement | Malvern Panalytical

Viscosity is an important property of fluids which describes a liquids resistance to flow and is related to the internal friction within the fluid. The most common type of flow behavior is shear flow where layers of fluid move relative to each another in response to a shearing force. This external force takes the form of a shear stress which is ...
