It arises from the off-diagonal terms in the fluctuation dot-product moment and, as such, is an inherently dissipative effect.
It arises from the off-diagonal terms in the fluctuation dot-product moment and, as such, is an inherently dissipative effect. It has two types, dynamic and kinematic, the latter being the former divided by the fluid density. Measured in cgs units in poise or stokes, a fluid is said to be ideal if this property is zero for it.  FTP, name this fundamental property of fluid flow; the internal resistance of a fluid to flow.
