kinematic viscosity
Fluid's momentum diffusivity
Kinematic viscosity is a fluid's resistance to flow under the influence of gravity, calculated by dividing dynamic viscosity by density.
It measures how quickly a fluid spreads when poured—honey has high kinematic viscosity, water has low.
The standard unit is the stoke or centistoke.
Engineers use it to characterize lubricants, fuels, and other fluids in motion.
