Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with the fluid mass density like. ν = μ / ρ (2) where . ν = kinematic viscosity (m 2 /s) μ = absolute or dynamic viscosity (N s/m 2) ρ = density (kg/m 3)
Kinematic viscosity is the ratio of - absolute or dynamic viscosity to density - a quantity in which no force is involved. Learn more about kinematic viscosity formula and related solved examples.
Kinematic viscosity can be computed by dividing the absolute viscosity of a fluid with the fluid mass density. Formula for Kinematic Viscosity. As we know that it is the ratio of dynamic viscosity to fluid mass density. Thus, Kinematic viscosity = \(\frac {Dynamic viscosity} {Fluid mass density}\) Mathematically, \(v = \frac { \mu } {\ rho }\)
The kinematic viscosity equation is: v=𝜇/p. where v = kinematic viscosity, 𝜇=dynamic viscosity, p =density. Kinematic viscosity is measured in units of (length) 2 /time – most commonly using centiStokes (cSt), where 1 Stoke = 1 cm 2 /s. When used in this equation, the viscosity μ is often referred to as dynamic viscosity or absolute viscosity.
The kinematic viscosity embraces both the viscosity and density properties of a fluid. The above equation shows that the dimensions of \(\nu\) to be square meter per second, \([m^2 / sec]\), which are acceleration units (a combination of kinematic terms).
The kinematic viscosity of water at 20 °C is about 1 cSt. The most frequently used systems of US customary, or Imperial, units are the British Gravitational (BG) and English Engineering (EE).
The formula for calculating kinematic viscosity is: \(ν = \frac{μ}{ρ}\), where 'μ' represents dynamic viscosity and 'ρ' is the fluid's density. Dynamic Viscosity, denoted as 'μ', is a measure of a fluid's inherent resistance to flow when an external force is applied.
In essence, kinematic viscosity is a measure of the resistive flow of a fluid under the influence of gravity. It is frequently measured using a device called a capillary viscometer — basically a graduated can with a narrow tube at the bottom.
Kinematic viscosity is the measure of the inherent resistance of a fluid to flow when no external force is exerted, except gravity. It is the ratio of the dynamic viscosity to its density, a force independent quantity. Kinematic viscosity can be obtained by dividing the absolute viscosity of a fluid with the fluid mass density.
The kinematic viscosity formula (ν = \frac{μ}{ρ}) is used extensively in fluid dynamics and engineering to calculate kinematic viscosity when dynamic viscosity (μ) and density (ρ) are known. Here are a few examples of how the formula is applied:
