Q3. It was decided to construct a fabric filter, using bags of 0.45 m diameter and 7.5 m long, for removing industrial stack gas containing particulates. The expected rate of airflow into the filter is 10m3 /s. If the filtering velocity is 2.0 m/min, the minimum number of bags (rounded to nearest higher integer) required for continuous cleaning operation is
Answer : Option B
Explaination / Solution:

Given, D=0.45m, L=7.5m
No. of fabric filter bags,
Total area of filter (Af) = (10 × 60)/2 = 300m2
Area of one bag (Ab) = πdL = π×0.45×7.5 = 10.60m2
N = 300/10.60 = 28.28 ~ 29
