Dynamic Vs Kinematic Viscosity

The main difference between dynamic and kinematic viscosity is that dynamic viscosity is a measurement of how difficult it is for a fluid to flow whereas kinematic viscosity is the dynamic viscosity of a fluid divided by its density. A basic difference between the dynamic and kinematic viscosity measurements is density.

Definition Of Kinematic Viscosity Properties Of Fluid Fluid

Kinematic viscosity in ssu versus dynamic or absolute viscosity can be expressed as.

Dynamic vs kinematic viscosity. Dynamic viscosity is the quantitative expression of fluid s resistance to flow while kinematic viscosity is the ratio of the fluid s viscous force to the inertial force. Dynamic viscosity is independent of the density of the fluid but kinematic viscosity depends on the density of the liquid. Dynamic and kinematic viscosity in fluid dynamics it is common to work in terms of the kinematic viscosity also called momentum diffusivity defined as the ratio of the viscosity μ to the density of the fluid ρ.

It is usually denoted by the greek letter nu ν and has dimension displaystyle mathrm length 2 time. Dynamic viscosity is flowed the newton 2nd law second law as per newton second law of motion. The formula for the conversion is.

Density actually provides a way to convert between a kinematic and a dynamic viscosity measurement. Kinematic viscosity is equal to the dynamic viscosity divided by the density of the liquid. The unit of measure of kinematic viscosity is centistokes cst.

Dynamic viscosity is symbolized by either âµ or n while kinematic viscosity is mathematically symbolized by v. ν ssu kinematic viscosity ssu b 4 632 for temperature 100 o f 37 8 o c b 4 664 for temperature 210 o f 98 9 o c μ dynamic or absolute viscosity cp. He says which relates the acceleration with the forces.

Due to the force exerted on the material the deformation causes the fluid fluid particle to move. The ratio of shear stress to shear strain is called dynamic viscosity and usually it is measured in centipoise cp and pa s is the unit of measurement. Science fluid kinematics viscosity studying only motion without thinking of force.
