no, not a problem... yyou just can't generate enough pressure (you probebly can get 1/2 psi)

Your lungs can produce about 5 psi, at least 20 is required for the valve to equalize and seal.

Psi: pounds per square inch

I kinda agree about that noname :lol: ! Where did you get the idea that it means you could blow a three pound object into the air??? With a pneumatic pumped to 100 psi could you shoot a 100 pound person into the air? No.

I geuss I could move it an inch in the air if the weights were on a frictionless 1x1 square piston that I was blowing into.

Evidently you have no idea what you're talking about.

ok, this is how I'm imagining it... a one inch pipe with a one inch metal rod that weighs 3 lb in it. I can't imagine blowing into it and haveing the rod lift.

Evidently we are thinking of two different examples.

now can you stop being an asshole, and tell me why the fuck you think I'm so stupid?

Psi and pounds are completely different. Pounds per square inch refers to the weight on each square inch of something. If you inflate your lungs all the way and keep breathing in more and more air little by little, the air in your lungs can be compressed up to around 5 psi. This does not in any way mean you can blow a 5 pound object into the air.

why does that matter? the thread is about how much pressure you can push out into the valve... whatever I don't care any more, you were just being aggresive for no reason.

Well excuse me, did you not say that if I could produce 3 psi, I could blow a 3 pound object into the air?
