The bending of the jet of a viscous fluid, outflowing from a capillary, under the joint action of the inertial, viscous, and surface tension forces of the fluid in it, was investigated. A linear model of the bending of such a jet is proposed. The dispersion relations have been obtained for the rate of increasing the disturbances of this jet. It is shown that the jet bends spontaneously. A qualitative analysis of the influence of the viscosity of a fluid and the velocity of its outflow from a capillary on the angle of deviation of the fluid jet formed from the capillary axis has been performed.
