Pressure vessel leakage - time to equalize

  1. Aug 1, 2008 #1
    Hi all, I have a problem I hope someone could help. I have a pressurized dry Nitrogen vessel. Given a known leakage rate, how long will it take for the internal pressure to be equal to atmospheric pressure?

    Take a look at Milton Beychok's web site for a good reference on this. It's a tricky problem when considering compressible, choked flow with a varying temperature due to expansion.
