A listed hood selection in this exercise specifies 300 cfm per linear foot for the stated appliance duty and mounting. For an 8-foot hood, what airflow follows from that supplied selection?
- A37.5 cfm
- 2,400 cfm
- C300 cfm
- D800 cfm
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why B is correct
8 × 300 = 2,400 cfm. The rate is specific to the stated selection; it is not a universal Texas hood rate.
