Abstract

The distribution of dynamic pressure in the depth of water flow reduction of dynamic pressure with a decrease in the vertical coordinate, maximum relative values in the near-surface layer of water. The distribution of dynamic pressure pulsations in the depth of water flow increases the ripple of dynamic pressure with a decrease in the vertical coordinate. The preliminary assessment of the magnitude of the forces caused by dynamic pressure is 270 grams for 1 cm², and its pulsations - 1 grade for 1 cm².
