单词 stokes
释义
stokes

Physics
  • Symbol St. A c.g.s. unit of kinematic viscosity equal to the ratio of the viscosity of a fluid in poises to its density in grams per cubic centimetre. 1 stokes = 10−4 m2 s−1. It is named after Sir George Gabriel Stokes.


Chemistry
  • A c.g.s. unit of kinematic viscosity equal to the ratio of the viscosity of a fluid in poises to its density in grams per cubic centimetre. 1 stokes = 10−4 m2 s−1. It is named after the British mathematician and physicist Sir George Gabriel Stokes (1819–1903).


Chemical Engineering
  • A c.g.s. unit of measure of the kinematic viscosity of a fluid expressed as the ratio of the viscosity, μ, in poise divided by the density, ρ, in grams per cubic centimetre:

    ν=μρ

    The units of centistokes, cSt, are more commonly used where 1 cSt is equal to 10−6 m2 s−1. The kinematic viscosity of water is exactly 1 cSt at 20.2ºC.
