Air consumption at depth

[Packhorse]

I have posted this on another tread but think it deserves its own

This is a speadsheet I made for calculating air consumption at various depths and how much you would use to return to the surface for 1 or 2 divers and also allows you to compair 2 tank sizes.
Numbers in green can be changed to suit your dives and tanks.
If anyone thinks I have made a mistake (or two) please let me know.

By the way its metric and I copyed the idea from someone who posted one in imperial.

oops. here it is

Nice!

How much of a hassle would it be to get you (or anyone else??) to make one in imperial units? The only thing I know how to do in Excel is plug in numbers, otherwise I'd have a go at it myself.

Nicely done.

Here's MY version for imperial units. The first page can be used to calculate RMV the second page for minimum ascent pressures. Please let me know if you see any errors or typos.

...and how much you would use to return to the surface for 1 or 2 divers...

On this board do a search for "Rock Bottom" for a far more complete discussion on gas mangement and when to begin your return to the surface.

Is there something in particular that you think I missed?

This is excellent, thanks!!

I was going to do something similar but simpler myself (just a list of depth and air required), but this is so much better.

Hey all thanks for the thread and Spread sheets. What would be considered a normal range for RMV? Mine was .515 for my last dive.

that's very good, Submariner. i am an air hog at .79

one of my dive buddies (Jeandiver) has .51 i believe.. something
obscene!
