The objective of this study is to verify how much the fluid mixture in the narrow tube such as He-Ar mixture is able to be separated using the acoustic vibration (the sound wave) in each tube diameter or sound frequency. To verify the separation of the He-Ar mixture, it was enclosed in the 4.8 mm narrow and 4.1 m long tube, and the 80.3 Hz and about 1.5 kPa sound wave was propagated in the tube. Helium quantity at the entrance of the narrow tube decreased and Helium quantity at the exit increased logarithmically. Hammering test was used to measure mixture ratio and the error was about 2.4%.
