In the field of jet technology a nozzle of a liquid-gas jet apparatus for feed of an active liquid medium has a central channel and a peripheral annular channel and the total surface area of the outlet cross-section of the nozzle channels is determined from the following formula: S=Smu(1+{square root over ((Skc/Smu)3)}), where S-is the total surface area of the outlet cross-section of the nozzle; Smu-is the surface area of the outlet cross-section of the central channel of the nozzle; and Skc-is the surface area of the minimal cross-section of the mixing chamber. A liquid-gas jet apparatus with the above-mentioned features has a higher efficiency and an improved reliability.
