Abstract
We present the results of theoretical and experimental investigations of the method for measuring surface tension. The method is based on the deformation of the surface of studied liquid by a gas jet. The criteria for choosing the parameters of aerodynamic action and a given value of the height of a cavity on the liquid surface are formulated. Due to the substantial influence of the density of liquid on the results of measurements, the method is recommended for the evaluation of the surface pressure of surface-active substances.
