Introduction to Fluid Mechanics
... 6. Viscosity is a measure of a fluid’s resistance to flow. Most simple fluids are represented well by Newton’s law of viscosity. The exceptions (non-Newtonian fluids) are generally complex mixtures, some of which are of great practical significance. Kinematic viscosity is viscosity divided by densit ...

Laminar and Turbulent Flow in Pipes

Therefore friction will occur between layers within the fluid. Fluids with a high viscosity will flow more slowly and will generally not support e ...
