Abstract
The mechanism of the effect of the atmosphere on the picture of the entrance of a body into water is discussed. The self-similar character of the motion of a spurting jet is demonstrated, and an evaluation is made of the aerodynamic forces acting on spurting jets, which explain the qualitative difference in the character of the motion of the liquid as a function of the density of the atmosphere. These results were set forth briefly in a paper by L. I. Sedov given at the XIII International Congress of Mechanical Engineers in Moscow in August, 1972.
