Key Terminology
-
Square millimeter/second (mm²/s)
-
A metric unit of kinematic viscosity indicating the rate of momentum diffusion through a fluid, numerically equal to 1 centistoke.
-
Square foot/hour (ft²/h)
-
An imperial unit of kinematic viscosity expressing the rate at which momentum diffuses through a fluid over time.
-
Kinematic viscosity
-
A measure of a fluid's resistance to flow and shear under gravitational forces, represented as dynamic viscosity divided by fluid density.
