Figure 3

Vibration amplitude-frequency curves and power spectra at different leakage locations. (a) The amplitude-frequency curve of leakage hole distance from pipeline inlet is 300 mm. (b) The power spectrum of leakage hole distance from pipeline inlet is 300 mm. (c) The amplitude-frequency curve of leakage hole distance from pipeline inlet is 450 mm. (d) The power spectrum of leakage hole distance from pipeline inlet is 450 mm. (e) The amplitude-frequency curve of leakage hole distance from pipeline inlet is 800 mm. (f) The power spectrum of leakage hole distance from pipeline inlet is 800 mm.
