A simple empirical equation of the minimum transport velocity of a dilute two-phase flow for granular solids in a vertical pipe has been derived on the basis of both a dynamic model equation and the transport experiment. The minimum transport velocity means here the limiting air velocity at which conveying is possible in a state in which particles are not stagnant or recircular in the pipe. As a result, it is found that the empirical equation of the minimum transport velocity, simply called the minimum velocity, can arrange the data of this study with a pretty good accuracy.
