Query: Equivalence of dynamical ensembles and Navier Stokes equations   A reversible version of the Navier Stokes equation is studied. A conjecture
emerges stating the equivalence between the reversible equation and the usual
Navier Stokes equation. The latter appears as a statement of ensembles
equivalence in the limit of infinite Reynolds number, which plays the role of
the thermodynamic limit.
