Let us say a divers SAC rate has been previously calculated at .75 FT3/min.
That Diver goes to 66 feet(3 ata), dives a square profile stays 30 mins
That diver uses (.75 X 30 X 3) = 67.5 cubic feet used.
Same diver, same time same square type profile at 99 feet(4 ata) (.75 X 30 X 4) = 90 cubic feet used.
