Yes, a little risky, but since the technical dive leader vetoed the use all the helium we just bought (unacceptable labeling!) all our dives were limited to rec depths.
If we were dealing with just an orifice or laminar flow element, would expect the flow rate to nearly quadruple with increasing ambient pressure.
Nice thing to hear
I'm simply curious about the helium thing. Is it too much to ask about further details? We always use the He-cylinders (after some beyond average customer probing) with questionable labeling for many 100s of dives since many years ;-)
Would the flow really be expected to quadruple in the above case to 47m? My crude testing of non fixated (non plugged) IP regulators on a small CMF flow does not indicate anyway near that sever increases in flow?
