Flow studies were conducted in 0.0266‐m and 0.0504‐m glass pipes held at various angles of inclination. Measurements in these experimental setups included particle velocities, solid mass flow rates, and pressure drops in both the upper and the lower halves of the pipe. Visual observations of the flow patterns were made through the glass section. Particles used in this system included glass particles of 67‐, 450‐, and 900‐μm diameter, as well as iron oxide of 400‐μm diameter. Mass flows from the two halves of the pipe were obtained by splitting the flow with a knife‐edged separator. Experiments were also performed in a 0.0095‐m transfer line in an inclined loop. The angle of inclination of the test loop was varied from 0 to 90 degrees from the horizontal. The effect of angle of loop inclination, tube diameter, and particle characteristics on basic flow parameters were studied.
