Trying to locate a thread.....

I tried searching and spent a good hour looking, but to no avail...

Some one posted either a chart, or their own assumption, as to how FAST an 80 will drain if an o-ring blows on the 1st stage at depth (75 ft+/-)...I kinda recall 74 seconds?

Did anyone book mark that post and can direct me?

TIA,

This?

I dont believe so, but informative nonetheless. Thank you!

Am I reading this correctly though? @ 99ft, the low pressure will drain in 81 seconds? And then what is the 14.45 cuft? I'm looking for failure numbers with an 80 tank...

How Long to Drain a 80 Cubic Foot Cylinder - 4 Failures

Google is the best way for me to search a site. I used "how fast does a 80 cu ft tank drain site:scubaboard.com" and this was the first link.

Of course, the table above is the same as the one in the article.

Yes. For all intents and purposes a HP or LP failure the depth is not relevant. That is the time differences are noise. That is not the case for a free flow.

Do the math.......Al 80 is 77.9 cuft. That’ll give you a good idea.
