This paper deals with visualization and geometrical analysis of flat water jet structures. The shadowgraphy method created by a CCD camera and high-energy pulsed laser, as well as the image analysis method were tested. The jet structures were captured in the centre of axis symmetry. The influence of water pressures on water clusters dimensions and droplets was studied. The designed diagnostic water line consisting of a pressure sensor and a turbine flowmeter was used for flow monitoring during experimental flow visualization. The impact pressures of impinging water clusters and droplets were measured in centre of the jet. The experimental tests were performed in the following range of operating conditions: water pressure up to 20 MPa at maximal flow rate of 39 l/min and hydraulic power of 13.32 kW. A linear relationship between the number of small droplets and the distance from the nozzle was analysed.
