Good vid. I've been wondering how drown resistant my boys are when their in their turn outs on our ship. I'm curious to know what the buoyancy would be in the salt chuck with a density of 1.025 to the standard 1.0 of fresh water (not sure if chlorination changes that density.)
Hi Frank, thank you so much for the great instruction! One question: to my understanding, the lung demand valve of the SCBA will continuously blow off unless it is not a specialised SCUBA device. How long will your air supply reach under these conditions, meaning how many minutes can you breathe underwater with a SCBA with a full bottle?
So that's a complicated question and depends heavily on the depth you are at (due to Boyle's law) and your own oxygen consumption rate. The SCBA will not continuously blow off as it is a demand valve and will only deliver air when you breathe it in, though. But the most simple answer is your dive time would be similar to what you get with a normal SCUBA system breathing normal air.
@@fett2288 Hey, thank you so much for the detailed answer. Never really thought about that question. Just know that I was taught as a recruit fire fighter 25 years ago that SCBAs do not work under water because they blow off due to the water pressure. Very interesting perspective. Will try to find more about that. Thank you very much
