Viscosity of Fluid

Viscosity measures the resistance a fluid offers to flow and deformation. It results from internal friction between layers of fluid moving relative to one another. Dynamic viscosity, denoted by the Greek letter mu (μ), quantifies the force needed to move one fluid layer over another. For Newtonian fluids like water and air, the relationship betw...

Viscosity measures how a fluid resists flowing due to internal friction when layers of the fluid move past each other.

For example, honey flows slowly because it has high viscosity, while water flows easily with low viscosity.

There are two main types of viscosity: dynamic and kinematic. Dynamic viscosity measures the force needed ...
