I am thinkin about converting my bbmg to portable and am wondering how long 4 feet of sch40 pipe charged up too 100psi will last.. If you understand what i am saying the plz reply.. Sort of hard to put in words..

You mean how long it will fire for, right? Well, that would depend on the diameter of the pipe. What diameter were you thinking?

[Dussalater]

yea 2" pipe
(message too short)

Right... well... umm... I have no idea. I've tried this with smaller diameter pipe and it didn't work... but mine was fail, sooo.... i'd say just go for it and figure it out

Probably 3 seconds before it hits about 50-60psi, where the BBMG will turn to sh|t.

If you want an answer to your question, give more information.

What are you using for a valve (blowgun?) ?

What are you using for a barrel? (1/4" brake line, or?)

These things will affect how long your pressure chamber is useful.

If it is already posted, you COULD post a link to it. Might make it easier for someone to help you?

The blowgun I was able to find specs for has a flow rate of about 30cfm at 90psi.

That's 28.8 in3 per second at 90 psi.

Your chamber volume is 301.4 in3

That means, you would run out of useable air in less than 10 seconds.

That sucks.

That sucks.

It would be better to have a regulated HPA or CO₂ supply, but it can still be fun
