A method for measuring the impedance matrix and the dynamic properties of liquid-filled flexible hose is described in this paper. Dynamic hose properties are presented for a wide range of hose types. Nylon-reinforced hoses are shown to have considerably lower bulk moduli and stiffnesses than steel-reinforced hoses. The dynamic bulk moduli and stiffnesses are shown to be significantly and consistently higher than the static values. These results may be used to give an estimate of representative properties for a hose, based on its maximum pressure rating and its type of reinforcement.
