I dunno la. Maybe if have 1 BAR at 30m, then on surface it should show 4 BAR. Correct? But can see 4 BAR on gauge meh?


SKK, this is the answer. If it has 0 BAR then it is empty unless there is some air left inside and the gauge cannot show this minute figure.

because u mentioned correct... so i thought u r not sure.. that's why i started another topic. and that since this question is not about spg operation, i thought of starting another fresh thread.

anyway, thanks for the answer and i'm so sorry for the yellow flag.
it wont happen again.
thanks .

hehe.. holemaster... i was going to ask that  ;)

btw.. SD... if u say u r 0 at 20m.... where can u still got air to breath and ascent to 5m to do safety stop some more?

sorry... i might have misunderstood u.

thanks.



Air expands as you go up.



kekeee... true .. thanks :)

hmm.. btw. .a silly question again... is it that... when u r at 30m.. your presure gauge show u 0... which means no air... but when u ascent to 20m, and since the theory says that u will have air and that air expands... will ur pressure gauge increase by a few bar indicating that u have air? :-?


Hmm...why don't you go down with Erra Fazira to 600m? You will know you will run out of air easily. Then tell me if air will expand.

My pressure gauge was always at 0.  Like I said, don't try this at home.

sorry if i have understood you wrongly.

i know that air will expand from 30m to 20m ... but my question is will a spg shows that ? ... like showing 0bar at 30m.. but when u r at 20m... the needle will show maybe 10bar or something...?  or is it the needle still showing 0bar but u have a bit of air to breath?

thanks


Let me guess what is happening here, the pressure gauge connects to the 1st stage in High Pressure hole, that's why the pressure gauge is not sensitive in low pressure range. Any suggestion?

Hehe..I don't use a transmitter. Remember? I don't believe in electronics mixing with water.

Average breath per BAR per diver...you can get that from the SAC rate/RMV of the diver.

what is RMV?

sorry.


Respiratory Minute Volume


Thanks SD ... its a new term to me and will find out more obout it

SKK .. yeah my friend told me pony bottle quite famous in the states.

Snuf and SD : Is there any possibility that a 0 bar tank (tottaly run out of air) at 25 mtr can
have few more air upon accending ???? or at the 1st stage, or at the host and the primary 2nd stage


Yes .. Pony Bottle are famous in the STATES

25m = 3.5 ATA

IP on 1st stage = 9.25bar-10bar

So as you have 0bar at 25m depth, when you ascend the ATA reduce & there be some or little air coming out from the regulator la.

Have a look at Pressure Gauge, is not giving low reading..... in 1bar-2bar, is reading 10bar...20bar....or 15bar...30bar so on.

YES...you are right, that is why is call High Pressure Gauge....0Bar-350Bar....0Bar-400Bar

Low Pressure Gauge ... 0psi-400psi/300psi

[highlight]SKK...have I blocked you from opening new threads? All I said was please do not start new threads unnecessarily as this particular thread is already discussing about what you wanted to ask..which was: if from 30m you go up will there be any air expanding in the tank?

That has already been answered in here about doing it from 20m or from whatever depth. If you do it from 600m too there will be air expanding in the regulator.

When you open up too many threads unnecessarily, you not only clutter the screen but you also move discussions to other pages when the same thing may need to be refered to an earlier posting in the original thread.

If you want to ask anything about diving single tank to 600m, then by all means start a new thread. But don't just start one, get 3-4 replies and start another one. Have meaningful discussions, please.[/highlight] ;)

I agree with SeaDemon.

SKK ... nobody [highlight]BAN or PREVENT [/highlight]you from opening new thread but please read through the answer given in it.

[highlight]I am sorry [/highlight]if the reply is slow on our behalf to your question, we will try to speed up the answer in the near future but PLEASE read through & some of the answer are in there.

Anyway I know SD are worried with you catching up to him ....  :D

Don't worry. Just ask what you need to ask, I trust you are doing something good here. I think SD is saying, keep 1 topic in a single thread for easy reference.  SD, Am I right?

j/k  ;) .. anyway sorry :)
but SD, just to let u know that.. i'm cumming coming  ;D

(anyway, will wait for the answer next time. [highlight]sorry[/highlight] for my mistake to open up too much thread... i was thinking that it's not related to this thread as, the title of this thread is Run out of air situation.... and it's not the same as pressure gauge reading. yes, i've read everything on all the thread that i will reply. it just that u mentioned "correct?", so i thought u r not sure. so, that was my 2nd reason to open another thread.)

I reaaly hope by end of this year I can get 2 professional certification, ie PMP (Project Management Professional) and DM. I know many ppl here might go against my idea of getting DM certification since I'm a new diver. I have yet to plan to change my career into diving related industry as well. The more certification course I've, the more diving knowledge I'll have. That's my thinking! It's just like fall in love then get married or vice-versa. I don't know...

So far I've talked to my instructor, he said is ok either way will do. Get more diving experience 1st or get a DM then dive for experience. I know there's a fiduciary duty being a DM and have to pay a fee every year. I really don't know, mayb you guys can give me some advise.  :-/ :-/ :-/
