Based on these numbers you probably found rice has a small angle of repose (around 25 to 30 degrees) whereas the powdered sugar has a relatively high angle (greater than 40 degrees).

All the experiments were performed at the same temperature/humidity environments (RH = 42.0% ± 1.5% and T = 21.3 ± 1.0 °C). GranuHeap. A heap is formed when a powder is poured onto a surface.

The prediction of the angle of repose for raised mounds of dry cohesive granular material is a long-standing problem in the natural sciences and in industry. Using numerical (particle-based ...
