WitrynaKinematic viscosity is widely established due to historical reasons: Gravity is constant anywhere on Earth and as a driving force, it does not need any elaborate technical equipment. The SI unit is either mm 2 /s or m 2 /s, where 1 m 2 /s = 1,000,000 mm 2 /s. The SI units can be derived from the kinematic viscosity equation: Witrynawhere is a shift constant, and and are empirical parameters.
