Abstract
It is possible to transport the conveyance of mixture fluids such as oil or high viscosity solution by using compressed air. However, when a pipe line length was short, slug velocity did not change and it became clear that slug velocity is increase became the pipe length get longer. Increase of slug velocity is a thing by a pressure drop, which is expansion of compressed air, but does not became clear about an effect of the air with a few studies for long pipe line. We examined the effect of pressure of compressed air in long distance conveyance and examined that is increase of slug velocity due to the expansion of air and pressure drop.
