Smaller vs Larger pipe sizes

I recently bought 10' of type L 1/2 inch copper pipe. I was wondering if it could withstand pressures of ~400 PSI. Would it have the same amount of power when compared to a 3/4 inch copper pipe when both charged at a same amount of psi?
Basically: Would it have more power than 3/4 inch air chamber?

Ummm... What are you on, and where can I get some?
I've really got no idea what you're talking about, could you please elaborate?

I just reread it, it sounded horrible T_T.

the smaller the bore the more pressures.

Hmm true. copper.org says it can withstand ~1090 or so.(Type L 1/2 inch)
Would it be more effective in propelling an object?

Funny..
I understood it as he was asking if a larger diameter copper pipe would hold the same amount of pressure as a smaller diameter pipe. Sort of like in PVC, a 1 in. diameter is rated somewhere in the neighborhood of 400 psi, but a 3" is less rated but more volume. I'm not familar with copper that much but if that's what he's asking, a program like GGDT would be nice to solve the dilemma of more volume, or more pressure..
Its your choice. That question has been around our department for years, on a two-stage pump, its either pressure or volume on our fire trucks..

well what cannon would it be if it can't propell an object?

Still no idea what you're asking...
1/2" copper of a given type (L in this case) is rated higher than 3/4" copper of the same type, but both would have no trouble with 400, or even 1 000 psi.
Obviously, if you have 2 chambers charged to 400 psi, and one has twice the volume of the other, there will be more potential energy in the larger one.

the things that affect the power of the gun are: the type of the valve you use (and its size) and the diameter and lenght of the barrel.. diameter of the chamber isn't as important...

are you aking if you use 3/4in unstead of 1/2in will it be more powerful
Well if so the answer is obviously the 3/4in will have a decent bit more power, the more volume the more power.
but if you didnt know that already than why are you doing this in the first place
But that may not be what you are asking...
