I just recently took my Basic Nitrox course and really got into it...maybe too into it. I'm starting my TDI advanced Nitrox and Deco Procedures, but since basic nitrox, I've become obsessed with learning more and more about gas laws and calculating Fractions of gas. On my own, I've figured out how to calculate tri mix based on planned depth and desired END of N2. This really just made me want to know more. So, based on some talk of our LDS considering carrying banked 40% Nitrox, I got to wondering how would I manually calculate certain fills. This should be simple, but it's just not turning out that way.
Say I have a partially filled tank and i want to fill it using 40% Nitrox and air as my top off gas. How would I go about calculating it? btw...I have a software program that figures it all out, but my goal is to totally understand it and be able to do it all manually.
Problem: HAVE: 80 ft3 cylinder filled with 400 psi of 32% Nitrox
Desire fill of 3000 psi of 34% Nitrox
Using 40% Nitrox(banked) and air as a top off gas
Can somebody walk me through these calculations?
Thanks
