On the basis of calculations of the pressure oscillation of a pipe system using transfer matrices, it has been experimentally established that the existing pipe model underestimates its dynamic damping. For practical use, the theoretical laminar model of D'Souza and Oldenberger has been thought to express the precise characteristics of the dynamic behaviour of the pipe. The authors have measured the dynamic characteristics of a centrifugal pump by using the hydraulic exciter. This report describes the successive experimental research to derermine the dynamic damping effect of the pipe. The measured damping term increased when the Reynolds number increased in the turbulent flow region, although they are almost the same as the theoretical model at the laminar flow region. The pipe transfer matrix model for the turbulent flow is proposed using the correlation of t he measured results and the equilalent kinematic viscosity.
