How to calculate total air consumption along ascent?

[dmaziuk]

If you assume a uniform breathing rate and a uniform ascent rate...

First, assume a perfectly spherical diver of uniform density.

wow, you've really let yourself go over lockdown!!! ;-)

What is the average depth between 10m and the surface? 5m
What is the average depth between 10m and the depth of the last breath taken before surfacing? Interesting?
Because the remaining few cm or m should not be counted to calculate the average depth? It plays no part at all.
Therefore if the last underwater breath was taken at 1m, the average of depth is 4.5m = 5.5m(10 -4.5)?
total : 15 x1.55 = 23.25.

Buy a Shearwater Perdix with AI and import the dive information in MacDive: The software will give you the information you are seeking all through your dive.

Assume my RMV is 15L/min on the surface, 30L/min at 10m.
If I ascent from 10m depth to surface, ascend rate is steady 10m/min,
how much air will I consume??

If my SAC is not constant, and my ascent rate is not constant,
how could I calculate my air consumption.

Please help solve this problem in University Calculus/Physics way,
my calculus skills are rusted but if you give me a hint, I might recall the memory....
thank you.

Is that some scuba homework?

We need the answer to 16 decimal places for complete irrelevance.

That’s more than a double
