Angle of Repose Calculator

The angle of repose is a direct measure of the aptness of material to flow: the lower the angle, the more the material flows (think about it: water has an angle of repose of 0 0 0: it flows so well!), while for higher angles we witness materials that oppose to flowing. The granulometry of a material is one of the core elements that affect the ...
