What is the volumn of nitrogen required per one foot of 16" pipe to pipe test at 180#of pressure

Do you mean: what is weight of nitrogen needed? Use the ideal gas law:

n= PV/RT = [180psi* 1.33^2 * pi/4 ft^3]/[10.73 ft^3 psi/R lb-mol * 520 deg R] * 454 g/lb = 20.35 mol

This assumes that the temp is 520 degrees R (about 59 degrees F).

The molecular weight of N2 is approximately 28 g/mol, so you need 28*20.35 = 570 grams, or 1.25 pounds.

188 ft at 2200 psi

How much nitrogen should I used

How much nitrgen should I use to test 188 ft pipeline

How do test pipeline test with nitrogen

If you know the diameter of the pipe you can use the same method to calculate how much nitrogen you need as described in post #2 of this thread.

I need the ,volumn
