How Can Velocity and Interstitial Velocity Differ in a Baghouse Filter
Can velocity and interstitial velocity are commonly confused when proper filter selection and baghouse sizing are being decided because they are very similar when filter bags extend to the hopper level. Can velocity is the vertical gas velocity throughout the housing, above the hopper level but before reaching the bottom of the bags. Interstitial velocity is the vertical gas velocity once the flow is at the bottom of the filter bags.
