Abstract
We introduce a three independent functions variational formalism for stationary and non-stationary barotropic flows. This is less than the four variables which appear in the standard equations of fluid dynamics which are the velocity field and the density . It will be shown how in terms of our new variable the Euler and continuity equations can be integrated in the stationary case.
