Kinematic Viscosity is defined to be dynamic viscosity (see poise) divided by the density of the liquid; this gives a quantity which depends only on the type of the liquid, independent of its concentration or density. The quotient turns out to have units length2 /time. Being a CGS unit, the stokes is therefore defined to be 1 cm2 /s, equivalent to 10-4 m2/s or 0.001 076 391 ft2 /s. |
