Kinematic Dynamic Viscosity

Viscosity is an important fluid property when analyzing liquid behavior and fluid motion near solid boundaries. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. The shear resistance in a fluid is caused by inter-molecular friction exerted when layers of fluid attempt to slide by one another. viscosity is the measure of a fluid’s resistance to flow molasses is highly viscous water is medium viscous gas is low viscous There are two related measures of fluid viscosity dynamic  ( or absolute ) kinematic Dynamic (absolute) Viscosity Absolute viscosity – coefficient of absolute viscosity – is a measure of internal resistance. Dynamic (absolute) viscosity is the tangential force per unit area required to move one horizontal plane with respect to an other plane – at an unit velocity – when maintaining an unit distance apart in the fluid. The shearing stress between the layers of a non turbulent fluid mov...
