Oops with HPA, will it be enough?

I hope you mean 144ci tank.  A 144cf tank would be something you'd SCUBA dive with.

You should get bare minimum about 1000 shots out of what you have left.  Probably more.

Shoot. That will be enough to last you a few weeks.

I am assuming there are 12 Cubic Inches in a Cubic Foot. So there are 1728CI in your tank. So therefore, at 4500 psi you should get about ~25000 shots off that tank. At 3000psi you should get about 17000 shots. If you have a 68 CI tank you should get about 25 fills off of that.*


*This is all assuming that my math isn't bassackwards. And that I have my units of measurment right.

EDIT:

Ok, so wikipedia is telling me there are 1728ci in one cf.

So if this is the case, You have 248,832ci in your tank.

You will get about 2,480,000 shots at 3000 psi.

You will get about 3,700,000 shots at 4500 psi.

You will get about 3800 fills.

Somehow that doesn't seem right, and I don't think its my math. Let me check wiki.

Just to give you an idea of where I got those numbers from.

Normally on a HPA tank you calcualte the number of shots you should get with this equation:

x=size of the tank in cubic inches.

y=number of shots.

For 3000psi tanks: 10*x=y.

For 4500psi tanks: 15*x=y. 

I just did some searching on wiki. We are all wrong. Dive tanks are not measured in any way that makes sense to a sane individual.

wiki wrote: In the US you might find a cylinder with an internal capacity of 0.4 ft³ filled to 3000 psi; Taking air pressure as 15 psi, this gives 0.4 x 3000 / 15 = 80 ft³ (although it would be described as an "80 cubic foot cylinder", as the US normally refers to cylinder capacity as free-air equivalent at its working pressure, rather than the internal volume of the cylinder commonly used in metric countries).

So therefore we would need The real capicity of the cylinder to make a good guess.
