N2 - The pressure loss of the flow with a moving bed is investigated theoretically and experimentally in this paper. Two kinds of experimental apparatus were used. One of them consists of three kinds of pipes of 30. 8, 39. 7, and 49. 6 mm i. d. , and the other consists of two kinds of pipes of 80. 2 and 105. 1 mm i. d. And two kinds of glass beads and PCV pellet were used in measuring pressure loss. The pressure increased as the mean velocity of mixture and the delivered concentration of solid increased, but the additional pressure loss due to the presence of solid is hardly affected by the mean velocity. It was ascertained from the result of analysis by this model that thrust force was the dominant factor for the pressure loss, but this force decreased with an increase in the mean velocity, and it was found that this result was due to the increase of the velocity ratio of particles to fluid.
