Title: Differential invariants of the 3-dimensional Navier-Stokes equations

We study flows of viscid Newtonian fluids in the gravity field that described by the system of the Navier-Stokes equations. Algebras of symmetries and differential invariants of the system at hand are found. The dependence of thermodynamical states on the algebra of admissible symmetries is studied.
