Answer:
The ACH is 12/h
Solution:
As per the question:
Area of the space, [tex]A_{s} = 100 ft^{2}[/tex]
Height of the given space, h = 10 ft
Air flow rate, [tex]Q_{a} = 200 cfm[/tex]
Now, to find the Air Change Rate (ACH):
We calculate the Volume of the given space:
[tex]V_{s} = A_{s}\times h = 100\times 10 = 1000 ft^{3}[/tex]
Now, the ACH per min:
= [tex]\frac{V_{s}}{Q_{a}} = \frac{1000}{200} = 5/min[/tex]
Now, ACH per hour:
= [tex]\frac{60}{5} = 12/h[/tex]
