Recently, the conduit transport using compressed air is attempted as a transportation method of emulsified oil, high viscosity solution. This transport system would be used in: compound of corpuscle and water such as seabed-dirt with comparatively high water content, crude petroleum that flowed into sea area with increased viscosity, and liquid that mixed algae in a high density of the freshwater lakes. Though the long distance conduit transportation is needed to achieve these transportations, the research of the corresponding long distance is extremely few. In this research, the experiments are set-upped by 620m for the longest length in the horizontal pipe, 38mm for the pipe diameter. We examined the effect of initial pressure of compressed air in long distance conveyance. As the results of the experiment, it was to clarify that the pipe length and initial pressure have the correlation. Prediction formula concerning the initial pressure was able to be required from these data.
