Analogous to Newton's equations of motion, the Navier Stokes equations describe changes in momentum ( force ) in response to pressure P and viscosity, parameterized, here, by the kinematic viscosity \ nu.

Unlike most dimensionless numbers used in the study of fluid mechanics, the Kapitza number represents a material property, as it is formed by combining powers of the surface tension, density, gravitational acceleration and kinematic viscosity.
33.
One can convert efflux time to kinematic viscosity by using an equation for each cup specification number, where " t " is the efflux time and " ? " is the kinematic viscosity in centistokes.

With kinematic viscosities of v = 10 " 6 m 2 s " 1 the Ekman number is several orders of magnitude smaller than unity; therefore, molecular frictional forces are certainly negligible for large-scale oceanic motions.
36.
Speed, kinematic viscosity and a characteristic length scale of the object are incorporated into a dimensionless quantity called the Reynolds number \ scriptstyle Re . \ scriptstyle C _ \ mathrm d \, is thus a function of \ scriptstyle Re.
37.
The friction factor is not a constant : it depends on such things as the characteristics of the pipe ( diameter and roughness height ), the characteristics of the fluid ( its kinematic viscosity [ nu ] ), and the velocity of the fluid flow.
38.
Where "'u "'( x, t ) is the flow field, p the pressure, ? the density of the fluid, ? the kinematic viscosity, ubd the velocity at the boundary, and us the velocity of the solid.
39.
For single non-winter grade oils, the kinematic viscosity is measured at a temperature of 100 �C ( 212 �F ) in units of mm 2 / s ( millimeter squared per second ) or the equivalent older non-SI units, centistokes ( abbreviated cSt ).
40.
Where " T " is absolute temperature in kelvins, \ nu is the kinematic viscosity in centistokes, K _ 0 is the zero order modified Bessel function of the second kind, and " A " and " B " are liquid specific values.
