WebSep 12, 2024 · 4.3: Rheology. Viscosity measurements are the realm of a field of science called rheology. Rheology is, literally, the study of flow. Another very simple definition, attributed to chemical engineer Chris Macosko at University of Minnesota, is the study of "what happens when you squish stuff". There's an element of force or pressure that … WebRheology. Oscillatory Shear measurements: By subjecting a specimen to an oscillatory stress (σ) and determining the response, both the elastic and viscous or damping characteristics can be obtained.

In this equation, [η] is the intrinsic viscosity; that's the viscosity attributed to the solute, rather than the viscosity of the solvent itself. M is the molecular weight. K and α are constants for a particular polymer.
