Drained angle of repose is determined by allowing an excess quantity of material positioned above a fixed diameter base to “drain” from the container. Formation of a cone of powder on the fixed diameter base allows determination of the drained angle of repose. Dynamic angle of repose is determined by filling a cylinder (with a clear, flat cover on one end) and rotating it at a specified speed.

8. Angle of Repose. Paddy forms a complete cone when it is vertically unloaded on a flat surface. The angle of the side of this cone-shaped mass of grain, measured after the flow of grain has completely stopped, is the angle of repose. This angle defers from each type of grain and depends much on the smoothness of the surface of the grain.
