Does this sound correct to anyone else?
Using air tables, we know that the amount of nitrogen absorbtion is multipied by the number of bar you dive.
33+ft (2 bar)= 2 x surface nitrogen
66+ft (3 bar) =3 x surface nitrogen
99+ft (4 bar)= 4 x surface nitrogen
So if
a dive to 100ft(4 bar) means you are absorbing 4 x the amount of nitrogen as the suface.
and a dive 50ft(2 bar) means you are absorbing 2 x the amount of nitrogen as the surface.
Then does it stand to reason that
If I multiply the time spent at lower depth by the multiple of the rate of nitrogen absorption (2,3,4 bar) at lower depth. I now have an equivalent nitrogen absorption time.
Dive to 100ft(4 bar)for 5 min, then accend to 50ft(2 bar) for ? minutes
5 min @ 100ft x 4 (bar) = 20 min @ 50ft(2 bar)
5 min x 4 bar =20 min @ 2 bar
Then I subtract that amount of time from the planned shallow dive time
50ft for 40min- 20min = 20 min left @50ft.
I have already included my safty stop by knock back the 50ft planned dive time from max to 40min.
just checking if that is right.
