EXPERIMENTAL STUDY OF THE POLYTROPE COEFFICIENT IN CASE OF HYDRAULIC IMPACT WITH AN AIR-WATER FLOW

The article presents the results of analytical and experimental study of the polytropic coefficient in the process of hydraulic shock with an air-water pressure flow. At the same time, a reliable coincidence of the results of calculating the polytropic coefficient by the proposed method with experimental data is obtained, which also confirms the variability of the polytropic coefficient during hydraulic shock in the air-water flow. The conducted experiments prove that the coefficient of polytropes is strictly polytropic in nature.
