Mployd Consulting Interview Questions and Answers

Bulk density is the mass of a powder per unit volume, while tapped density is the mass of a powder per unit volume after tapping. Compressibility index is a measure of the powder's ability to be compressed.

• Bulk density is determined by measuring the mass of a known volume of powder.

• Tapped density is determined by measuring the mass of a known volume of powder after tapping it a specified number of times.

• Compressibility index is calculated by subtracting the tapped density fro...read more
