I did the math a few years ago.

Ya that was a great thread. Is five years a few? For some reason that link doesnt work for me. Here is the one I had marked that works for me.

Lohman, read this thread and see the last post By RobAGD he made a nice chart on the Wt. difference between Air and Argon.

You're off a decimal place. The math I posted above was done by a chemical engineer and then verified.

Didn't know you were a chem-e (Edit: Nevermind, I read the other thread).

Anyhow; cool, I was right.

Thanks guys. Manike chimed in on the thread in PBN, and since its the Invert forum that basically ended the argument off

I got into this argument twice in the past month with different PBNers. Both proclaiming an advantage of using HPA over co2 was the fact a co2 tank is 16oz heavier when filled, and the HPA doesn't get heavier.

The sad part is that despite all logical evidence, most other PBN members agreed with them.
Somebody needs to explode that server.

Looks like you were right. I did the math again today because I thought I was crazy, and I must have typed in something wrong. I was off on the decimal.

i had an argument with a 43 year old machinest about hpa having weight, it took a dive master to settle it and prove to him there was weight

anybody who's ever had to lug around a an 80+ or 100+ CF tank KNOWS theres a weight difference.
