## 3000 & 6000psi

hi all
How would nitrogen behave at 3000psi? or 6000psi?
assuming it starts at liquid form and at 1 atms pressure heated to 20 Celsius.

thank you

However , critical pressure at which Nitrogen can be liquefied is 34 atms. Critical temperature to liquefy Nitrogen is 140 oC . Both these conditions must be simultaneously met to properly liquefy Nitrogen. So you cannot get liquid form of Nitrogen at 1 atm pressure heated to 20 Celsius.

3000 or 6000 psi is too big the pressure !!

I think definitely this pressure will convert Nitrogen to liquid or probably solid even.

Google for "phase diagram for nitrogen" or some such, and you'll find diagrams such asthe following: http://www.wolframalpha.com/input/?i...+phase+diagram

You may have to do some conversion of units to get your answer.

sankalpmittal, i dont think it will turn to solid since i found a few companies using high nitrogen pressure for different uses such as this machine:

Nugatory, your link looks promising thank you. What is the difference between "phase diagram" and "vapor pressure rate"?
 The pressure in compressed gas cylinders used in labs are around 3000 psi. Nitrogen is still gas at these pressures and room temperature. Even 6000 psi is not so unusual: http://www.mmr-tech.com/PDFs/NitrogenGasSpec_TSB001.pdf
