1	Nitrox Stik Oxygen Useage Spreadsheet
2
3	Edit the fields in yellow to determine how many tank fills you get from one oxygen cylinder
4
5	Oxygen Cylinder Size (CUFT)		Desired Nitrox Mix (%)		SCUBA Tank size (CUFT)		# of Tank Fills per Oxygen Cylinder
6	250		32		77.4		26.4
7
8	Aluminum 80's in fact contain 77.4 cuft of air at 3000 psi
9	This spreadsheet assumes that the Scuba tank has 500 psi before filling, and that you are filling 5/6 of the total tank capacity
10	This spreadsheet assumes that the Oxygen Cylinder is initially filled to 2200 psi and that it is returned with 100 psi remaining, meaning you can use 21/22 of the total cylinder capacity.
