A classroom ventilation exercise specifies a people component of 10 cfm per occupant. With 30 occupants, what is that component alone?
- A3 cfm
- 300 cfm
- C30 cfm
- D3,000 cfm
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why B is correct
30 × 10 = 300 cfm. This is only the specified people component; any area component and system adjustments are outside the calculation.
