A review on the angle of repose of granular materials

Five different laboratories participated in this study each of the laboratories employed two operators to measure the angle of repose of a mold powder and each operator repeated the measurement three tim As a result the maximum repeatability of the 95 confidence interval was within 14 176 while the maximum reproducibility of the 95

Angle of repose Wikipedia

The angle of repose or critical angle of repose of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping At this angle the material on the slope face is on the verge of sliding The angle of repose can range from 0 176 to 90 176
