Hi everyone, this is my first post here. It looks like this is a great community so I am hoping for some help in either a better explanation or different approach to my problem: How can you determine the size of a hole in a container that is filled with gas given the starting pressure, ending pressure, time interval between starting and ending, density of the gas, and volume of the container? I found a reference but after playing around with the equations I couldn't get it to work out to the same answer the authors did. I don't know if there is an error in their work or if I am making a mistake figuring it out (probably the latter). Anyway, here is the reference where I got my equations from: http://www.piug.org.uk/IUGNewsletter3-2.pdf , pages 2 to 3. They get an answer of 472 microns, when I calculate it I get 459 microns. I am trying to set it up in excel so I can enter different values and have it calculate the hole size for any given leak rate.(adsbygoogle = window.adsbygoogle || []).push({});

I hope I explained this clearly, thanks in advance for any and all suggestions.
