kinematic viscosity
kinematic viscosity n (General Physics) a measure of the resistance to flow of a fluid, equal to its absolute viscosity divided by its density. Symbol: ν Kinematic Viscosity
kinematic viscosity[¦kin·ə¦mad·ik vi′skäs·əd·ē] (fluid mechanics) The absolute viscosity of a fluid divided by its density. Also known as coefficient of kinematic viscosity. Kinematic Viscosity (also kinematic modulus of viscosity), the ratio of the conventional modulus of viscosity η (also called the dynamic coefficient) to the density of the substance ρ; it is designated by ν. In the International System of Units the unit of kinematic viscosity is m2/sec. A fractional unit of kinematic viscosity, cm2/sec, is called the stokes: 1 m2/sec = 104 stokes. kinematic viscosity
kin·e·mat·ic vis·cos·i·ty (ν, Υ), a measure used in studies of fluid flow: dynamic viscosity, μ, in poises, divided by the density of the fluid; unit of measure: stoke.
