Web2 okt. 2024 · What is face velocity? ASHRAE 110 defines face velocity as the average velocity of air moving perpendicular to the hood face, usually expressed in feet per minute (FPM) or meters per second (MPS). It is a simple measure of air going into the fume hood. In the Laboratory Ventilation Standard, ANSI/AIHA Z9.5 (page 22) it says: WebThis occurs in Phase III when the acceleration linearly decreases until it reaches zero. In Phase IV, the control velocity is constant until deceleration begins, at which point the profiles decelerates in a manner symmetric to Phases I, II and III. A trapezoidal profile, on the other hand, has 3 phases. It is a subset of an S-curve profile ...

Webstop [9]. If the initial velocity v0 is greater than the maximum velocity: s·v0 > s·vr, the velocity has to be reduced to vr. In this case, ar = −s · amax and we have a double deceleration proﬁle where a rand d have the same sign [9]. Finally, we determine suitable values for Ta, Td and Tv.
