Powder Flowability Index Calculator

Carr's Index & Hausner Ratio for powder flow assessment

Enter Powder Density Values

Mass of powder divided by its bulk volume

Mass of powder divided by its tapped volume

Quick Samples

Formulae

Carr's Index = (ρₜ - ρᵦ)/ρₜ × 100

Hausner Ratio = ρₜ / ρᵦ

ρₜ = tapped density, ρᵦ = bulk density

Applications

  • • Tablet manufacturing
  • • Capsule filling
  • • Powder blending
  • • Quality control

Factors Affecting Flow

  • • Particle size & distribution
  • • Particle shape & surface texture
  • • Moisture content
  • • Cohesive forces
