With increase in gas flow rate to fabric surface area ratio (Nm3/hr/m2 fabric surface area), the size & the cost of a bag filter___________________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remain unaffected
- D. None of these
Explanation
A higher gas-to-cloth ratio means more gas passes through each unit area of filter cloth, so less cloth area and a smaller, cheaper filter are required. The trade-off is a higher pressure drop and potentially greater dust loading.
