There are four groups of variables that influence dust collector performance. They are variables regarding: 1. dust, 2. fluid, 3. operation, 4. Dust Collector. Variables regarding dust are size, shape, density of dust particles, and agglomerating tendency Variables regarding fluid are density and viscosity. These are functions of air or gas composition, temperature, and barometric pressure. The effect of dust and fluid variables can be simplified by using the terminal velocity theory. Terminal settling velocity, commonly called terminal velocity or "settling velocity”, is the velocity of a particle, falling in still air or another fluid, after it stops accelerating. So it is clearly determined by dust and fluid’s properties. Variables regarding operation are gas velocity through the collector, or capacity in cubic feet per minute, and dust loading, generally...
