Viscosity is the resistance to shear or flow in a fluid – and a measure of the adhesive/cohesive or frictional property. The viscosity that arises due to internal molecular friction produces the frictional drag effect.
There are two related measures of fluid viscosity – known as dynamic viscosity (or absolute ) e kinematics .
Kinematic viscosities of some common liquids:
| Liquid | is the maximum pressure to be reached at the discharge | Kinematic viscosity | ||
