Key Terminology
-
Attostokes (aSt)
-
A unit of kinematic viscosity equal to 10^-18 stokes, used to represent extremely low viscosity values at molecular or nanoscale levels.
-
Stokes (St)
-
The CGS unit of kinematic viscosity defined as one square centimetre per second, commonly used to specify fluid resistance to flow.
-
Kinematic Viscosity
-
A measure of momentum diffusivity of a fluid, calculated as dynamic viscosity divided by density, indicating how quickly momentum is transported.
