The Hausner ratio is a dimensionless number that compares the tapped bulk density to the loose bulk density of a particulate solid. It is widely used in process engineering to quantify powder flowability: a low ratio indicates free-flowing, while a high ratio reveals cohesive behavior. Typical applications include hopper and silo design, tablet formulation, and pneumatic conveying.
