  Hydrodynamics of gases in the classical domain are examined from the
perspective that the gas has a well-defined wavefunction description at all
times. Specifically, the internal energy and volume exclusion of decorrelated
vortex structures are included so that quantum corrections and modifications to
Navier-Stokes behavior can be derived. This leads to a small deviation in rigid
body rotation for a cylindrically bound gas and the internal energy changes
associated with vorticity give deviations in the Reynolds' transport theorem.
Some macroscopic observable features arising from this include variations in
the specific heat, an anisotropic correction to thermal conductivity and a
variation in optical scattering as a function of the declination from the axis
of local vorticity. The improvements in magneto-optical traps suggests some
interesting experiments to be done in higher temperature regimes where they are
not usually employed. It is argued that the finite lifetime of observed
vortices in ultracold bosonic gases is only apparent and these volume excluding
structures persist in generating angular momentum and pressure in the cloud in
a non-imageable form.
