Abstract: The problem of pipe conveying fluid under vibrational effect took a very fine and precise attention because of the importance of vibrational affected fluid behavior. Experimentally work was carried out on building a rig of gravitational flow under the effect of excitation by vibrated force placed on different locations beneath the pipe end for different frequencies. The rig was provided with the necessary measurement equipment to study the effect of vibration on the discharge time. It has been proven, experimentally that the position and value of excited vibration have effect on the discharge time. The minimum discharge time registered at maximum stiffness and in excited frequency nearest from the natural frequency (shaker at 18.5 cm of clamped end) and for 25 rad/sec frequency.
