| Abstract: | The influences of liquid column length, pulsation frequency and viscosity on oscillation amplitude of liquid surface are aralyzed by solving the differential equation of motion for liquid column in U- tube. The results show that U -tube can be used to measure mean pressure difference for pulsating gas flow in the intake pipe of internal combustion engine under certain conditions. |

| Keywords: | U-tube pulsating gas flow liquid surface |
