The Carr Index is a measure used to assess the compressibility and flowability of powders, crucial for industries dealing with bulk materials. It quantifies the difference between the aerated and tapped bulk densities of a powder, providing insight into its handling and processing characteristics.

Compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure change. It is a critical property in fields such as fluid dynamics and material science, influencing how substances behave under different pressure conditions.

Compressibility

Flowability refers to the ease with which a material, particularly a powder or granular substance, moves or flows under specified conditions. It is a critical property in industries like pharmaceuticals, food processing, and manufacturing, affecting the efficiency and quality of production processes.

Handling characteristics refer to how a vehicle responds to driver inputs and road conditions, encompassing aspects like stability, maneuverability, and control. These characteristics are influenced by factors such as suspension design, weight distribution, and tire performance, which collectively determine the driving experience and safety.
