Filtering velocity V = Q/ (A *N) Where V = Filtering velocity in m/s Q = Air flow rate in M3/s or CFM A = Cross sectional area of the bag filter housings in m2 or ft2 N = Number of Bags If Q = 5000 CFM A = 50 ft2 N = 50 Then V = 5000 CFM / (50 ft2 * 50) V = 2 fpm ( feet per minute)
Good job 👍👌👌👍👍👌 bro
How to know filtering velocity. ?
Filtering velocity V = Q/ (A *N)
Where
V = Filtering velocity in m/s
Q = Air flow rate in M3/s or CFM
A = Cross sectional area of the bag filter housings in m2 or ft2
N = Number of Bags
If Q = 5000 CFM
A = 50 ft2
N = 50
Then
V = 5000 CFM / (50 ft2 * 50)
V = 2 fpm ( feet per minute)
