Key Terminology
-
Gigapoise (GP)
-
A large multiple of the poise from the CGS system to measure dynamic viscosity; 1 GP equals 10^9 poise or 100,000,000 pascal second.
-
Pascal second (Pa·s)
-
The SI derived unit of dynamic viscosity representing one pascal of shear stress per unit shear rate; equivalent to 1 N·s/m².
-
Dynamic viscosity
-
A property quantifying the shear stress needed to produce a unit shear rate in a fluid.
