Abstract As a necessary step in formulating a coherent set of angled standpipe design equations, the flow of powder and gas through the bottom restriction of a standpipe set at 45°, 60°, 75°, and 90° to the horizontal has been studied. Equations already successfully applied to vertical standpipe restrictions are shown to be equally accurate in describing inclined standpipe restrictions regardless of the angle of inclination. At high aeration rates (in both inclined and vertical standpipes), bubbles emerged which flowed down through the bottom restriction. This condition did not affect the relationship between the solids flow rate and the orifice pressure drop, but reduced the dependence of gas flow rate on these two variables.
