Kinematic Viscosity Calculator

The viscosity of a fluid is an important property in the analysis of liquid behavior and fluid motion near solid boundaries. Viscosity refers to the measure of a fluid’s resistance to flow. The Kinematic Viscosity is defined as the coefficient of viscosity of a fluid divided by the density. Kinematic Viscosity is measured in stokes. Kinematic viscosity is the most common viscosity measurement.

Nsm-2
m2s-1
kgm-3

Formula

v = m/p

Where,
v = Kinematic Viscosity [m2s-1]
m = Dynamic Viscosity [Nsm-2]
ρ = Density [kgm-3]

An oil's viscosity decreases with increase in temperature and increases when the temperature is reduced. Kinematic viscosity is expressed in centistokes (cSt) and is usually measured at 40°C, but can be measured at 100°C as well. This advanced online Kinematic Viscosity Calculator is used to calculate and find the kinematic viscosity of fluid.

Example:
Calculate the kinematic viscosity fluid by the given details of dynamic viscosity and density.
Dynamic Viscosity = 15 Nsm-2
Density = 10 m2s-1

Solution:
Apply Formula:
v = m/p
v = 15/10
v = 1.5 kgm-3
Kinematic Viscosity = 1.5 kgm-3
