There was examined a high-gradient rate of water stream in the paper. For its examination at rotary pump work they were changing the load meaning owing to elements causing a considerable heterogeneity in the stream, that is using backings made of small porcelain and glass balls with the diameters of 1 and 2 cm. For the modeling they used different content of hydrogen peroxide in water to reveal its subsequent influence on chemical and physical water behavior in before-cavitational and cavitational rates of stream with high gradients of speed. The acid rate was imitated with the help of sulphuric acid.
