big scuba tank?

Question

how bigto measure would a 6 ft tall scuba tank be in cf, or whatever they use it

Answer 1

To answer this question you will have to know the diameter of the tank the height and the working presssure. Because you have only given the height I will answer it based on what I can deduce.
First find the actual volume of the cylinder empty and use this formula
Assuming you have a K-Bottle which is 6ft high, 1 ft dia. and can be pressurized to 2400 PSI
Volume = π • r² • height = ¼ • π • d² • height

V= 3.14*(.5' * .5') * 6' = 4.71 Cubic feet empty


Given this we next apply this formula
V = 2,414.7 (psia=2400psi + 14.7psi pressure at sea level) 4.71(cubic feet) / 14.7 (each atmosphere equals 14.7 psi )or
V= 2414.7 * 4.71 / 14.7
V=773.689 cf
or round up to 774 cf

If you were pressurizing to 3000psi it would be
V= (3000psi + 14.7 psi )*4.71cf / 14.7
V=965.03 cf

Hope this helps

Answer 2

Depending on the diameter and the working pressure of the tank, approximately 160 cubic feet of air.
