This blog post will explore five of the fundamental measuring techniques for obtaining the dynamic viscosity and the kinematic viscosity of fluidic samples. This property is density-dependent and is measured in square meters per second (m 2/s). Kinematic viscosity refers to the resistive flow of a fluid under the influence of gravity.This characteristic is typically expressed in millipascal seconds (mPa-s). Dynamic viscosity is a measure of the shear stress per unit area required before a sample begins to deform.
Shear viscosity is expressed under two distinct forms: These Van der Waals forces are critical facets of a sample’s resistance to deformation, or flow, which defines the material’s viscosity. The viscous properties of a liquid or amorphous solid are primarily determined by inter-particle forces within the solution, including friction and attraction between molecules in the macrostructure.
