Angle of Repose - an overview | ScienceDirect Topics
The angle of repose (Fig. 7) is a parameter commonly used for the evaluation of interparticle force. 16 The simplest method for the determination of the angle of repose is the “poured” angle. A funnel with a wide outlet is affixed at a distance of 10 cm above the bench, where a piece of paper is placed directly beneath the funnel.
