Investigating flow properties of materials, e.g. viscosity or plasticity; Analysing materials by determining flow properties

Classification Context

Section:

PHYSICS

Class:

MEASURING; TESTING

Subclass:

INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES

Scope Notes

Glossary: viscosity resistance of a fluid to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. plasticity ability of certain solids to flow or to change shape permanently when subjected to stresses of intermediate magnitude between those producing temporary deformation, or elastic behaviour, and those causing failure of the material, or rupture. | Application references: measuring characteristics of blood in vivo, e.g. blood viscosity, for medical or veterinary diagnosis
