jjsteffen:Now, even your protege, MS whatever has thrown in the towel due to the inability to provide logical responses to his posts.
Yes, I have thrown in the towel. Your idol is a moron and you a lemming. By the way, what is the relevance of "5 dives"? To demonstrate you ARE a recreational diver I imagine. If Danny-boy wants to quote from his OW book and quote "real" divers (cause he ain't), I am pleased to let him. Its when he speaks from his own intrepretation that I have difficulty especially when he tries to attack others. This thread is laden with stupid Danisms just have a read. I have noticed how he doesn't try to defend those comments.
Dan the answer to the math discrepancy you hold so dear to your cause of justifying you as a diver is:
From your post I read this...
"When you consider a Luxfer S080 goes from 2 lb to +4 lb bouyant with air, you can see that using 21/35 would reduce the initial negative bouyancy to -0.2 lb."
I didn't verify your math. Nor, did I read your links to "other" sources. I am sure they are informative.
I should have tried harder to interpret what you are trying to articulate. I just skimmed the post ,<- my mistake.
The difference IS less than 2lbs, I mean WHOPPING 2 lbs.
By the way, one could easily do this in their head.
He is weighs 1/7 that of nitrogen (close enough). taking the volume of gas represented in PSI in a given cylinder we can merely divide by 7.
eg. 21/35 in an 80 @ 3000psi
to simplify let say nitrogen is .076 lb/cuft
I will also simplify by saying your 35% is roughly a third of the total. (accurate enough for the filling methods commonly used)
<start>
1/3 of 80 is 27cuft
27 * .076 = 2 pounds of Nitrogen
2 / 7 = .3 lbs of He
difference 1.7 lbs
<finish>
GEEWIZ that was easy!
So we're less than a 2 lb difference. That is close enough for rock and roll baby! And my stages are still not affected in the least! Do you think it has to do with my SS plate? ha!
