Viscosity is a measure of the internal fluid friction that causes resistance to flow. It is defined as the shear stress required to produce unit rate of shear strain.
In SI units, viscosity is expressed in Ns/m2.
Effect of Temperature on Viscosity of Water and Air
The viscosity of water decreases with the increase of temperature.
The viscosity of air increases with the increase of temperature.
