Oxygen Flow in tubing

[Fifie]

Help Required

I have a flow problem I would appreciate some help with.

I have oxygen @ 12 psi, a 12" length of 0.125" Bore pvc tubing.

Question ???

What Will this deliver in Liters/minute or cubic feet/min

assuming operating temperature is approx 25 deg C
6 l/min would give you a pressure drop of 0.44 psi

What I am trying to find out is will the 0.125 2 ID tube deliver 15 Ltrs a minute of oxygen @ 12PSI

It is for a medical device the oxygen enters into a face mask

Pressure loss is not an issue

No! to deliver 15 l/min you would need to increase the pressure or the tube id.
