This paper describes an experimental investigation of the stability of elastic pipes containing water flow, the velocity of which is perturbed harmonically about a mean value. Parametric and combination resonances were found to occur over specific ranges of pulsation amplitudes and frequencies, and of flow rates. The critical values of pulsation frequency and amplitude for the onset of instability are compared with theory, and agreement is found to be generally fairly good.
