Key Terminology
-
Dynamic viscosity
-
A measure of a fluid's resistance to shear flow, indicating its thickness or internal friction.
-
Pound-force second/sq. foot
-
An Imperial unit quantifying dynamic viscosity as the shear force per area per velocity gradient.
-
Hectopoise [hP]
-
A metric multiple of the poise, equal to 10 pascal-seconds, used to measure high dynamic viscosities.
