A baghouse filter has to treat 12 m3/s of waste gas continuously. The baghouse is to be divided into 5 sections of equal cloth area such that one section can be shut down for cleaning and/or repairing, while the other 4 sections continue to operate. An air-to-cloth ratio of 6.0 m3/min-m2 cloth will provide sufficient treatment to the gas. The individual bags are of 32 cm in diameter and 5 m in length. The total number of bags (in integer) required in the baghouse is
Correct answer is '30'. Can you explain this answer?

Understanding the Baghouse Filter Requirements
To determine the total number of bags required for the baghouse filter, we need to follow these steps:
1. Calculate the Total Cloth Area Needed
- The total flow rate to be treated is 12 m3/s.
- Convert the air-to-cloth ratio from m3/min-m2 to m3/s-m2:
- 6.0 m3/min-m2 = 6.0/60 m3/s-m2 = 0.1 m3/s-m2.
- The total cloth area (A) required can be calculated using the formula:
A = Total flow rate / Air-to-cloth ratio
A = 12 m3/s / 0.1 m3/s-m2 = 120 m2.
2. Determine the Area of One Bag
- The bags are cylindrical with a diameter of 32 cm and a length of 5 m.
- Convert the diameter to meters: 32 cm = 0.32 m.
- Calculate the radius (r) of the bag:
r = diameter/2 = 0.32 m / 2 = 0.16 m.
- The surface area (S) of one bag (without end caps) is calculated using the formula:
S = 2 * π * r * height.
S = 2 * π * 0.16 m * 5 m ≈ 5.03 m2.
3. Calculate Total Number of Bags Required
- The total number of bags (N) needed can be determined by:
N = Total cloth area / Area of one bag.
N = 120 m2 / 5.03 m2 ≈ 23.9.
- Since the number of bags must be a whole number, we round up to 24 bags for full operational capacity.
4. Adjust for Sectional Operation
- The baghouse is divided into 5 sections, allowing one section to be offline for maintenance.
- Therefore, each section must account for the total required cloth area:
Number of bags per section = Total number of bags / Number of sections = 24 bags / 4 operational sections = 6 bags per section.
Final Calculation
- Total number of bags required for continuous operation across all sections is:
6 bags/section * 5 sections = 30 bags.
Thus, the total number of bags required in the baghouse filter is 30.
To determine the total number of bags required for the baghouse filter, we need to follow these steps:

A = 12 m3/s / 0.1 m3/s-m2 = 120 m2.

Thus, the total number of bags required in the baghouse filter is 30.

Surface area of each filter bag = ? x 0.32 x 5 = 5.026m2
Surface area of filter required = (12 x 60)/6 = 120m2
Total working bags required = 120/5.026 = 24
Total bags required = 5/4 x 24 = 30
