Received: May 26, 2014
DOI: 10.7868/S0044451014120177
Hidden symmetry in dissipationless terms of arbitrary hydrodynamics equations is recognized. We demonstrate that all fluxes are generated by a single function and derive conventional Euler equations using the proposed formalism. Contribution for the JETP special issue in honor of A. F. Andreev's 75th birthday}
