Afraid the prey has slipped the hook, the wily fisherman gives the line a quick set of jerks.
Foxfish when I say cross referenced I mean I did the metric calculation and then used a conversion factor to CHECK my metric calculation from the imperial one and yes it was slightly different (to be expected) Storker used a faster time to surface than I did, causing his calculation to equal EXACTLY 80B, mine was a slightly more conservative ascent rate and caused it to be 86B, because you cant read 86B on a gauge I rounded up. Again they make a difference of making the surface or not making the surface before running out of gas, your choice. I'd prefer to come home without running out of gas in an emergency, I'd also like to use a gas plan where tank choice doesn't matter in determining pressure. I can see that you're going to stick to your ways and I just hope that some people reading this thread got something out of it and saw or learned that minimum gas calculations are useful.
With that, unless there is a huge need to, I am done posting in this thread. I hope some people are now using min gas laws, foxfish I can see you never will so good luck diving to you. You're gonna need it.
I imagine this being said in the voice of Robb Webb. I'm not sure if it should be like this or like this, thoughAfraid the prey has slipped the hook, the wily fisherman gives the line a quick set of jerks.
I estimated that using the 50 b method, you'd need to start an ascent at around 80 b for a 12 L tank from 30 m
Foxfish, I've honestly never seen a grown person more hard headed and argumentative in my life.
There fixed it for you.
While the recent changes in the course lays it out for the instructor, many will be learning for the first time, it was taught in my IDC in the early 90's. Not RB and the calculations that are being discussed here but a 'simpler' version but still more complex than be back with 500 psi.
