Ref. article by Geoff Guzynski as On-line extra to Issue 230, he states that in 5 minutes of spraying he will move 1,000kg (a tonne) of air through his spray gun.
That seems an awfully powerful spray gun – at approx 1kg/m^3 air density, that is 200,000L/min … how does he hold onto the gun?
Now if he was spraying water at a 1,000 time the density, maybe the figures work out, but not with air.
Unless I read Wikipedia wrong as well …

Ha, Ha, Ha
That's awesome ! I am not going to do the math. A little solvent goes a long way for me. I don't need the head aches and general poisoning of my body. Some like it though.
Risk ? You mean like from a lacquer explosion or just that your kids won't recognize you because their brains stopped working cause they have to breath the stuff in the house ?
Don't take me too seriously I didn't read the article.
Dangerous Miscalculation?
Given the subject (inflammability) this seems like a potentially dangerous miscalculation.
With a small fan in a booth like the accompanying picture, I could imagine a 1000 cubic feet of air in five minutes, but not 1000 kg. Since air is about 0.037 kg/cubic foot, the resulting concentration could be about 27 times higher with my assumed unit correction. But mine is just a wild guess. What are the correct units and calculation?
