Abstract

The authors tried to develop upon the hydraulic conveyor an analytical method for the pressure drop in the pneumatic conveyor by T.Uematsu and T.kano, and obtained a formula for the pressure drop in the "hold up flow" through a horizonta1 pipe. The experimental constant η' in the formula was determined by the results of experiments in flyash and sand slurries. The resulting formulas are in a good agreement with the authors' result and other investigators' also within the errors of measurement.
