Big Helium bottles... where?

[barbara.w.]

Missing Square

The correct formula for that volume of a tube is pi x half the diameter x height.

Wrong again.

 

[Tamborista]

Volume = pr<SUP>2 </SUP>h

r=radius
h=height of the cylinder
Pi=3.14

How many tanks do you need?

I don't think it will be much, but I need to secure an ongoing supply.

Hey. I was/am looking into keeping a 4.5 cubic meter balloon.
I have yet to find out how much liquid Helium will fill this volume with gas and then, I'd need to always keep that equal amount of liquid Helium at hand to adjust for loss over time and maybe re-fill.

The problem HERE so far is, that none of the suppliers agrees to accept the basics of physics. They insist on selling their gas bottles not by volume (liters, gallons) or weight (lbs, kilos) of LIQUID gas in their bottles but by at how much pressure they are filled, speaking of x-pesos per PSI! This is obviously a complete joke as pressure is not a prove of volume or quantity... a small container of, for the examples sake one cubic inch, if built solid can take a filling of thousands of PSI's... the volume thou still being 1 cubic inch.

Feel free to PM me if you have an idea.

Thanks! ... J-D.
