    "abstract": "The modern form of the Saint-Venant - Wantzel formula for an outflow velocity\nof gas stream from flowing element is submitted. Taking into account of contact\ninteraction of gas stream with the streamline surface in the form of the static\nhead law has allowed to find the spatial-energy liaison in flowing system. The\nphysically correct combination of mechanics of contact interaction and\nthermodynamics of fluid medium in one formula has allowed simultaneously to be\nliberated from the velocity coefficient and the discharge coefficient and\npolytropic process. In the new form the formula has gained the key character\nfor computation of parameters of motion and state of gas stream in the flowing\nsystem.",
