The research of the water dispersion parameters in impact with a hard dry and wetted surface was made. Noted best water spraying at surface with high roughness. This may be due to the difficulty of the air outlet from under flat (before impact) drops during impact. The share of dispersed liquid upon impact a teardrop-shaped expanding jet ( 40% of the water flow in the jet ) with wooden batten was investigated. Also was determined the radius of scattering droplets depending on the fall height and of the water flow consumption from the nozzle.
