Abstract : The transport of solid particles by air through a 0.0508 m pipe was studied in vertical, horizontal, and 45 deg orientations. Through control of the air humidity, the effects of electrostatic charging was observed. Pressure drop and particle velocities were measured. Particles used included 79 micrometer, 125 micrometer, and 450 micrometer glass beads and 128 micrometer Plexiglas beads. Analysis of particle velocity, pressure drop fluctuation, electrostatic pressure drop, choking, and saltation was performed. Visual observations of the flow patterns and behavior were made. A linear stability analysis for the three orientations was performed.
