- Summary:
- Need to find the hole size for an an allowable leak in a small, low pressure vessel.

Hello, all. I am completely new here so please be gentle.

I have a small, cylindrical, sealed ("no leak") pressure vessel with an approximate volume of 27 cm

I feel like this isn't that hard of a problem and I should probably know how to do it, but alas I've been out or school for awhile and I do not. And I haven't been able to find anything in my internet searches that seem to tackle this problem. Most of what I can find deals with water and the Bernoulli equation, but I don't think that applies here. I'm pretty sure I'm missing some information/data. I'm not necessarily looking for an exact answer, but mostly just how to do this as I may need to do other versions of this in the future. Thank you in advance.

^{3}. It has a constant supply of air pressure at 8"WC. I'm trying to figure out how big of a hole it can have if there is an allowable leak/flow rate of 1.00 sccm.I feel like this isn't that hard of a problem and I should probably know how to do it, but alas I've been out or school for awhile and I do not.
