dude... theyre scuba tanks. all scuba tanks are measured in cubic feet. you have 40, 50, 60, 80 and the monster 110. go to a dive shop. or look it up online. and you're right, they don't weigh 300 pounds. but the buggers are extremely heavy when linked. if you can, go to a dive shop and ask if they have a pair of 50 or 60's on a bc or backplate for you to try on. do a lap around the store and see what i mean.
no disrespection, but i know my stuff. i'm the one wearing it in the picture. lol. and if you think that sounds heavy, try wearing a single 20lb c02 with a steel tank surrounding the 20 pounds of liquid c02.
ps- it is compressed air... not measured as a liquid. a 100Ci/5000 bomber tank from specops doesnt weigh 50 pounds does it? well then... a scuba tank doesnt weigh 150 pounds either. i think your math is off. lol.
i mean... dude.... you're refuting A PICTURE!!!! do i need to make a video or something? ROFL
Mhmm. My scuba tanks over here are measured in litres.
Had a double-linked 14 liter / 3000 psi system just this weekend.
Here is the math I've done:
1,1 liter (68ci) of 4500psi compressed air weighs about 315 gramms. (Possible source of mistake)
2/3 of 315 grams mean 210 grams per 1,1 liter at 3000psi.
That's 191 grams per 1 liter. (Researched a tad bit, it's even 240 grams (at 20░C / 68░F). But even with the wrong value, the result is overwhelming)
60 cubic foot would be 60 * 28,3 liters. Or 1698 liters.
1689 liters * 191 grams ~ 324 kilograms.
Enlighten me. I am sure I have a fault there, but I can't see where.
Oh, and because it didn't come out right, I suppose: I don't doubt you carrying these beasts. Just the value of 60 cubic feet at 3000psi.
