    "abstract": "It is shown, that the introduction in Saint-Venant -Wantzel formula radicand\nof the free component in the form of quadrate of velocity of the incident gas\nflow on inlet of flowing element that was offered in the end of the XIX century\nand is remained till now it is physically inadequate. It is shown that this way\nis doubtful for hydromechanics and it absolutely is not reasonably for\ngasdynamics. Physically exact form of writing of static head law for flowing\nelement and relevant to this, the modern form of Saint-Venant - Wantzel formula\nare submitted ad-hoc. The obtained expressions allow physically correctly to\ntake into account both combined and isolated influence of pressure drop\napplying to the flowing element and velocity of incident gas flow on flowing\nelement, on quantity of the outflow velocity of gas stream out of this flowing\nelement, system. The obtained expressions are valid for a subsonic velocity of\nthe incident gas flow. The particular expressions are obtained for liquid.",
