Key Terminology
-
Dekapoise (daP)
-
A cgs-derived dynamic viscosity unit equal to 10 poise, equivalent to 1 pascal-second, used for measuring fluid resistance to shear flow.
-
Newton Second per Square Meter (N·s/m²)
-
The SI unit of dynamic viscosity representing a fluid’s internal resistance to shear, numerically equal to one pascal-second.
-
Dynamic Viscosity
-
A measure of a fluid's internal friction or resistance to flow under shear stress.
