Stoke

stoke

[stōk]

(fluid mechanics)

A unit of kinematic viscosity, equal to the kinematic viscosity of a fluid with a dynamic viscosity of 1 poise and a density of 1 gram per cubic centimeter. Symbol St (formerly S). Also known as lentor (deprecated usage); stokes.

Stoke

 

a unit of kinematic viscosity in the centimeter-gram-second system of units. A stoke is equal to the kinematic viscosity present when the dynamic viscosity of a medium with a density of 1 g/cm³ is equal to 1 poise. Named in honor of G. G. Stokes, the stoke is abbreviated St; 1 St = 1 cm²/sec = 10^–4m²/sec. In practice, a unit 100 times less than the stoke, the centistoke, is often used.
