Calculated critical collision velocity for equal-size agglomerates versus the cumulative percentage. This percentage is based on the number of detached particles/total number of detached particles ratio, as shown in Fig. 6a. Solid, dashed, dotted, and dashed and dotted lines show 50 μm glass beads, 100 μm glass beads, alumina particles, and silica sand, respectively
