抄録

This paper is divided into two parts. In the first part, we derived a theoretical formula, with which one can calculate the presure drop in the horizontal, vertical and bent pipes not only for the steady case, but also for the accelerating state. In the second part, we observed the behavior of particles in the bent pipe with various curvatures and investigated the re1ations among the mixture ratio of solid particles and air, the accelerating coefficient of particles and the curvature of bent pipe experimentally. From the results of these investigations, it has been concluded that (1) with the increase of the mixture ratio, the accelerating coefficient of particles decreases very rapidly, (2) the effect of the mixture ratio on the accelerating coefficient of particles is remarkable in a bent pipe with intensely shorp curve.
