What does Fluid viscosity mean?

Fluid Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighboring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called fluidity, a measure of the ease of flow.

Mean free path

The mean free path can be defined as the average distance the molecule travels between successive collisions.
