The problems of hydraulic transportation in pipe were studied and discussed by many authors, but fundamental. study of movement and behavior of a single particle in pipe were not yet carried out in Japan.
The authors analysed this probleme experimentally referring to the experimental results of Smolyzuilev in Russia, and obtained many new relations between parameters of a single particle transportation in pipe, that is, relations between velocity of a particle, mean velocity of water in pipe, specific weight of particles, and size of particles and pipe etc. were obtained.
These relations reveal us characteristic of behavior of a single particle in water pipe.
