WebFour commonly reported methods for testing powder flow are (1) angle of repose, (2) compressibility index or Hausner ratio, (3) flow rate through an orifice, and (4) shear cell. In addition, numerous variations of each of … The Hausner ratio is a number that is correlated to the flowability of a powder or granular material. It is named after the engineer Henry H. Hausner (1900–1995). The Hausner ratio is calculated by the formula where is the freely settled bulk density of the powder, and is the tapped bulk density of the powder. The Hausner ratio is not an absolute property of a material; its value can vary depending on the …
