How to calculate the angle of repose | eHow UK

The equation for calculating the angle of repose is: tan1 (2h/d). Using your scientific calculator, multiply height ("h" calculated in Step 2) by 2 and divide this value by the distance ("d" calculated in Step 3). Then, hit the inverse tan key (or tan1) and the answer just calculated. This will give you the angle of repose.

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.
