The paper proposes a derivation of general distinctive acoustic parameters of the hydrodynamic vibration system elements. The parameters of the system generating the high-speed waterjet, have been derived from the analogy of vibration systems and air medium behavior. These are the acoustic plasticity and acoustic mass as primary parameters for calculation of the theoretical resonation frequency with turbulent water-flow. Because waterjet shows different attributes than air-flow, these attributes have to be respected in compliance with experimental results. Frequency model (5 kHz to 10 kHz) refers to the interpolation for the liquid pressure range from 5 MPa to 25 MPa.
