Hi Nick!
Check out section 6-22, at the title "Compressible flow".
I used equations 6-118 and 6-122

Clearly, the holes are below the liquid surface and I want the same air mass flow. Air is not a liquid. There is no hole above the liquid surface. Where did you get that from? Please read instead of guessing. Lastly, I already solved the problem, which I stated.
I noticed the equation you provided is only applicable for incompressible fluids. This leads me to believe I have to find another way of solving this. Any ideas?
The change in depth will only be maximum 2 meters so maybe the pressure difference isn't significant. I'll try the test setup in a few days, then we'll see if the flow rate really differs at the different depths.
Thank you for being helpful! I really appreciate it

Thank you very much! I realized that all holes will have the same Cd so if I just guess what the Cd is, I can compare the different holes and calculate the estimated flow rate from there. You say that I can estimate the flow rate by dividing the total flow rate with the number of outlets. Is...
No it's not a homework problem. I'm building a test setup for a company, that consists of a tank with multiple holes and want to ensure that the mass flow through every hole is equal.
Hello! I will try to formulate myself as clearly as possible, but english isn't my main language. I'm having trouble solving this problem that should be relatively easy to solve.
Let's say we have a submerged pressure tank, constantly fed with air through a compressor, so it's maintained at a...
