Measurement of Friction Coefficient on a Powder Layer and Fluid Dynamic Study

Appendix-2: Density and magnified images of  used powders

Bulk density and magnified images of powders used in experiments are shown.

Bulk density is the mass of powder filling a container divided by the volume of the container. It is measured both in sieved and compressed state for  flour and potato starch.
