NITROGEN USE DURING PRV TESTING

[JAlton]

I am using a 2200 psi DOT Bottle to fill a 3 cubic foot, 3000 psi, Test Vessel.
The bottle has 230 cubic feet of nitrogen. How many times can I fill the 3 cubic foot vessel before the DOT bottle is empty? Seems it would depend on the PRV Set Pressure? If so, 125 psi, 650 psi and 1440 psi are typical. Thanks.

Boyles law: (P1xV1)/T1 = (P2xV2)/T2 should give an approximate value.
