Density, denoting the relationship between mass and volume or weight and volume, is a crucial metric for systems that link weight to volume, particularly in mixing or dispensing applications.

It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...

Powder is a collection of single solid particles, which in most cases may be considered a basic unit. Powder is typically comprised of solid particles, interparticle voids, as well as open and closed ...

A study on predicting acid-gas densities for the pressure and temperature ranges relevant to acid-gas injection schemes found that only one common equation of state gave unsatisfactory results.
