Fluid flow in water jet cannon for models of ideal incompressible and compressible fluid was investigated. The impact of fluid compressibility on the parameters of water jet cannon of concrete facilities was investigated. Numerical calculations for compressible fluid were performed using Rodionov method. The influence of density and compressibility on water jet cannon parameters was estimated. The distributions of fluid velocity and pressure at different stages of the process were obtained. The parameters that characterize the efficiency of water jet cannon, compared with the corresponding values for the water charge, were calculated. The complex evaluation of water jet cannon efficiency for working fluids with different density and compressibility was performed.
