Measurement of drag reduction and frequency analysis of the wall pressure fluctuation in pipe flow are carried out using dilute polymer solutions and aqueous detergent solutions in order to discuss the correlation between drag reduction and pressure fluctuation. Frequency analysis indicates that the power spectrum density of the pressure fluctuation of dilute polymer solutions is greater in the low-frequency region and less above 30[Hz] than that of water (solvent). Moreover, the level of pressure fluctuation in dilute polymer solutions is on the whole greater than that in water.
