How much energy is stored in HPA tank?

[AcemanPB]

I was wondering if any knows how much energy is stored in a 68/4500 tank

And if anyone feels like explaining to me how and what formulas to use to get the number I would be very thankful

[FalconGuy016]

I can find this out... hold on (ill be back to edit)

68x4500=306000psi.?

No.

And lets just say that it is enough energy to blow your arm off if you dis-respect it for even a split second or mistreat the fiber-wrapping

[AcemanPB]

Well I do know

Work = Pressure(Pa) x Change in volume(m^3)


4500psi = 31026410 Pa

I'm not to sure about change in volume I'm going from .00111432 cubic meters (or 68cu inches) to what? This formula also doesn't take into account the heat or any other factors that would play a role

I think he said it best

Yes I know this but I'm curious and want to know exactly how much energy we are talking here

[rifleman]

Well, I've kinda wondered about this myself and I'm not sure if energy is even the right term to measure it.

E = force * distance
which is:
Energy = mass * distance/time/time * distance

Well your mass is easy enough to figure out. I 'think' you'd have to find the velocity and acceleration of the molecules moving within the tank--which is directly proportional to the volume and temperature of the tank.

so in other words... hell if i know

[rifleman]

^ That equation is for potential energy.. but it may be kinetic energy we're measuring since the molecules 'are' moving inside the tank.

So relate to this ke = .5 * mass * velocity^2

But still, you'd have to find the velocity of the molecules.

in 68ci at 4500psi, multiply the two, you have 306000 lb-in or 25500 foot-lb. One Horse power is 33,000 foot lb per min. same energy as running 1hp motor for 46.4sec.
that is lot of energy. When tank bursts, it is releasing this instantly.(fraction of sec)

25500 foot lb, assuming that you are 255lb wil lift you up 100ft or 10 stories.


One horse is lot of energy. it is 746watt of energy. 746joule/sec

it is same as 34587 joule of energy in that tank.

1 joule is 1newton moving 1 meter.

1 newton is 1kg, 1m/sec^2

umm.......I like pie!


I understood very little of that, although it is complettely fasinating.

you people have to to much on your mind.

In short it could rip your arm off.

-It could be argued instead, that you don't have enough.
