WebAngle of Repose A material’s angle of repose is the angle at which material can be piled onto a horizontal plane before it begins to slide against itself, and is a result of how the factors above combine to influence how a material moves against itself. A material’s angle of repose is often used as an indication of its flowability. Webexcess quantity of material positioned above a fixed di-repose, α, from the following equation: ameter base to “drain” from the container. Formation of a cone of powder on the fixed diameter base allows tan (α) = height/0.5 base determination of the drained angle of repose. • Dynamic angle of repose is determined by filling a cylin-der ...
