Smoke Extraction System
Got an email today for a request to price out a smoke extraction system. (2) 40,000 CFM fans for this atrium.
This is the window they want to use for the gravity makeup air. 2'x8' louver at 80,000 CFM is a 46.5" WC pressure drop, or 1.7PSI!!!
Did you tell him that you'll do it IF he sucks a golf ball through a garden hose?

If you really know how it works, you have an execellent chance of fixin' er up!
Tomorrow is promised to no one...
Tell them they have 3 options:
1) Supply a larger air inlet
2) Reduce CFM requirements
3) Install vacuum pumps instead of blowers.
4) To hit the 5000fpm required, a large 200HP blower will be mounted in the window with a similar size blower on the roof.
