The article deals with an important issue of efficiency of using energy supplied into each of the elements of the Venturi-type pipe, i.e. the value of energy efficiency coefficient. The issue coverage requires conducting comparative studies of the specific surface area of bubbles in a gas-liquid system and the mass transfer coefficients in a pipe with a periodically changing cross-section and in a cylindrical pipe with other conditions being equal. The proposed method of excitation of pulsations in a moving fluid flow can be used for the processes of splitting droplets and bubbles in a continuous liquid phase, since this creates favorable conditions - significant amplitudes of pressure, speed and acceleration at a frequency of about dozens of Hertz.
