where \ k _ B \, is Boltzmann coefficient, \ T \, is the absolute temperature, and \ \ eta \, the dynamic viscosity of the surrounding fluid.
Air density must be calculated in order to solve for the pressure, and is used in calculating dynamic pressure for moving vehicles . kinematic viscosity is calculated by dividing dynamic viscosity by the density.
where a is the radius of the disk, g is the acceleration due to Earth's gravity, \ mu the dynamic viscosity of air, and M the mass of the disk.
where \ rho is the particle density, d is the grain diameter, \ dot { \ gamma } is the shear rate and \ mu is the dynamic viscosity of the interstitial fluid.

The ratio \ frac { dv } { dt } depends on R as the capillary radius, on the average applied pressure P, on its length L and on the dynamic viscosity ?.
Both bulk viscosity and dynamic viscosity need not be constant in general, they depend on density, on each other ( the viscosity is expressed in pressure ), and in compressible flows also on temperature.
where " ?" is the dynamic viscosity of the liquid, " V " is a characteristic velocity and \ sigma is the surface tension or interfacial tension between the two fluid phases.
*The water must have a constant density, dynamic viscosity ( and consequently temperature ) throughout the modelling domain ( SEAWAT is a modified version of MODFLOW which is designed for density-dependent groundwater flow and transport)
For a bearing to have its nominal lifespan at its nominal maximum load, it must be lubricated with a lubricant ( oil or grease ) that has at least the minimum dynamic viscosity ( usually denoted with the Greek letter \ nu ) recommended for that bearing.
