[F] 909.7.1 Velocity
JUMP TO FULL CODE CHAPTER
The minimum average velocity through a fixed opening shall not be less than:
| v = 217.2[h(Tf - To)/(Tf + 460)]1/2 | (Equation 9-2) |
For SI: = 119.9 [h (Tf - To)/Tf]1/2
where:
| h | = | Height of opening, feet (m). |
| Tf | = | Temperature of smoke, °F (K). |
| To | = | Temperature of ambient air, °F (K). |
| v | = | Air velocity, feet per minute (m/minute). |
