The operating pressure drop range in a bag filter is about ______________ mm water gauge?
Correct answer: A. 50-150
- A. 50-150
- B. 5-10
- C. 500-1500
- D. 1500-2500
Explanation
Bag filters normally operate with a pressure drop of roughly 50–150 mm water gauge, which increases as dust accumulates on the filter medium. The other ranges are either too low for normal operation or excessively high.
