Predicting gas leak at altitude

  1. Sep 30, 2010 #1
    I have a (faulty!) cylinder filled with compressed air at 2,000 psi which leaks at a rate of 1litre/minute at sea level. What would be the expected rate of leak at an altitude of 8,000ft? thanks for your help.

    Sounds like homework, perhaps you had better show some attempt at a solution before we help you...

    Um... I don't see this as homework because the answer is way too simple. The answer is there's no change in flow rate. The flow is choked so there's no increase in flow with a decrease in outlet pressure.
