The definition and difference between kinematic and dynamic viscosity have been discussed above in length. The kinematic viscosity of an oil is explained according to its resistance to flow and shear force under gravity Observing viscosity is important to oil analysis. Where, µ- dynamic or absolute viscosity, ρ- density The formula of kinematic viscosity: v=µ/ρ Kinematic viscosity is a measurement of a fluid’s internal resistance to go along under a gravitational force.į- Force, A- Area of each plate, u/y- a rate of shear deformation, µ- viscosity of the fluid. The theory of viscosity indicates a struggle against a flowing which is being misshapen due to some external shear force applied to it. However, temperature increases with the decreasing density of a liquid.Īpart from the difference between kinematic and dynamic viscosity, students can get a precise idea about the definition of viscosity and how the concept of density differs from the kinematic density of a liquid, students can follow the table below:ĭifference Between Viscosity and Kinematic Viscosity Moreover, the velocity of the spheres increases with the density of a fluid. Viscosity is measured in Pascal seconds, i.e. Δρ= difference of density of the fluid and tested sphere Velocity gradient- the difference between the adjoining layers of liquid Note: Shearing stress- If a direction of external force on an object is parallel to an object's plane, deformation will be along the plane and pressure felt on the object is considered shear stress. If we rest a sphere, into a liquid, we can evaluate the density by using the formula mentioned below: The density of a liquid is estimated based on a ratio of shearing stress to its velocity gradient. Below explained the symbols and terms used to calculate viscosity.

The unit centistokes (cST) has its applications in various fields.Īfter knowing units of densities, it is essential to learn how to calculate densities. Poise (P) is used explicitly in ASTM standards as centipoises (cP).

Since there are several types of density and each has its unit, to differentiate between dynamic viscosity and kinematic viscosity in units, students can use Poise (P) as the CGS unit of dynamic density and Stokes (St) as the CGs unit of kinematic viscosity. Sometimes students are asked about units of viscosities.

Now that students have collected some knowledge about viscosity and the difference between kinematic and dynamic viscosity, students must know about the different viscosity units. That external force (F) is proportional to Shear rate (SR), Dynamic Viscosity (η), and Surface area (A). The internal resistance of a liquid flow suggests an external force applied in the movement of a liquid.

Kinematic viscosity is a more fundamental property.Īpart from the difference between dynamic viscosity and kinematic viscosity, a few relations of this concept should be cleared. It is utilized when inertia and viscous force are dominant.ĭynamic force is utilized only when viscous force is dominant. This represents the ratio between shear stress to shear strain. This represents the ratio between dynamic viscosities to density. The symbol of the kinematic viscosity is V. Whereas, dynamic viscosity represents the viscous force of the liquid It represents the inertia as well as the viscous force of the fluid. It gives more information about the force required to make the liquid flow at a specific rate. To be precise, it explains how fast the liquid is moving when a certain amount of external force is applied. This is defined as the diffusivity of momentum.
