A filter baghouse is to process 15 m3/s of waste gas. The baghouse is to be divided into eight section of equal cloth area so that one section can be shut down for cleaning and/or repair while the others continue operating. Laboratory analysis indicate an air to-cloth ratio of 9.0 m3/min/m2.cloth will provided sufficient treatment. The bags are 0.25 m in diameter and 7.0 m long. The number of bags for the above physical arrangement to meet the requirement will be _________.
    Correct answer is '24'. Can you explain this answer?
    Verified Answer
    A filter baghouse is to process 15 m3/s of waste gas. The baghouse is ...
    Flow of air = 15 m3/s
    Air to cloth ratio = 9 m3/min/m2 cloth.
    ∴Area of colth rqurired = 
    = 100 m2.
    Also, Area of each bag = π DH
    = 3.14 × 0.25 × 7
    = 5.5 m2
    ∴Number of bag requried = 
    = 18.19
    Since baghouse is to be divided into eight equal section of equal cloth area so that one section can be shut down for cleaning or repair.
    ∴ Minimum number of bags required
    = 3 × 8 = 24

    Calculation of Cloth Area:

    - Given, waste gas flow rate = 15 m3/s
    - To divide into 8 sections, the flow rate per section = 15/8 = 1.875 m3/s
    - Air to-cloth ratio = 9.0 m3/min/m2
    - Convert flow rate per section into m3/min = 1.875 x 60 = 112.5 m3/min
    - Cloth area required per section = (112.5/9) = 12.5 m2

    Calculation of Number of Bags:

    - Diameter of each bag = 0.25 m
    - Length of each bag = 7.0 m
    - Surface area of each bag = π x 0.25 x 7.0 = 1.75 m2
    - Number of bags required per section = 12.5/1.75 = 7.14 (round off to the nearest integer)
    - Total number of bags required for 8 sections = 8 x 7 = 56
    - However, one section can be shut down for cleaning and/or repair while the others continue operating, so the number of bags required = 7 x 3 = 21
    - Adding a few extra bags for redundancy, the total number of bags required = 21 + 3 = 24
