The difference between Pressure & Volume - It should be noted that the
pressure of a tank is not a measure of the
size or
volume
of a tank. For example, most aluminum tanks, from the smallest 6 cuft pony bottle to an 80
cuft tank, have a fill pressure of 3000 psi. For a 6 cuft bottle, this means at 3000 psi
the tank contains 6 cuft of air. For an 80 cuft bottle this means at 3000 psi the tank
contains 80 cuft of air. Tanks come in a variety of combinations of volumes and fill
pressures but the
cubic foot (cuft) volume is the measure of how
much air a tank holds.
