exhaust Calculation

[edenriquez0601]

is this the correct computation for exhaust

example:

floor area A
bldg height B
product vol C

Ventilation
Air Change D

Exhaust fan A x B x C x D / 60

= CFM Exhaust fan

- You said area is A=7276 sq.ft how did you calculate it.
- why did you choose C as 50%
- how did you calculate supply cfm

If you have a computer background, why are you sizing a ventilation system? To answer your question and calculations do not sound right or make much sense.

Its a loading bay, so some things to consider. how many trucks are loading at a time? are the trucks engine running while loading or only some of them? do you use forklift to load? if yes, are they battery or gas engine driven? reason being is that you have to consider their exhaust too?
In fairness to you and all the guys here, They tried to help but with your limited knowledge in the dynamics of ventilation, We can only help you so much.
All the best.
