Kinetic Viscosity can be represented as the ration between dynamic viscosity and density.ĭynamic Viscosity is the representation of the viscous force of the fluid. It is represented as the ratio between the sheer strees and sheer strain The symbol of Kinetic Viscosity is v, and the unit of it is m 2/s The Symbol of Dynamic Viscosity is µ, and the unit of it is Ns/m 2 Whereas, Kinetic Viscosity is also know Absolute Viscosity. The video below explains this: Viscosity Detailed Video Explanation:ĭynamic Viscocity can also be known as Absolute Viscosity. It can also be expressed as the tangential force per unit area required to move the fluid in a horizontal plane relative to another plane, with a unit value velocity while the molecules of the fluid maintain a distance unitary each on the other. Therefore, dynamic viscosity is the force required for fluid to overcome its internal molecular friction so that the fluid can flow. Viscosity acts as an important property of fluid when analyzing fluid behaviour and fluid movement near solid limits.It is a type of tangential force that acts when one horizontal plane moves with another.
