Abstract
The motion of a liquid column in a vertical pipe caused by a moving piston touching its lower boundary is considered. The law of motion of the piston is set on the basis of experimental data. The acceleration of the piston exceeds the acceleration due to gravity. Liquid separation from the piston and the change in the cavitation-pocket volume are admitted. The simplest model of the phenomenon is proposed. A qualitative analytical solution of the one-dimensional problem and a comparison with experimental data are provided.
