So if you do find the necessary math to solve this, be sure to anticipate some possible problems in manufacturing or use, and find the sensitivity of the flow at the holes to these variations. | |

Due to that, finding an analytical solution can get very hard. As an example, if your holes are big enough and not far apart enough, the whole flow becomes kind of messy and the common equations start becoming more and more imprecise. You can read about Darcy-weisbach equation and head loss coefficients to get an idea of how such losses are usually estimated with a nice enough flow. | |

I'm still interested in a theoretical solution for various sizes of pipes and holes, so I'll try to migrate the question as you've suggested. As a new contributor here, I can't migrate the question on my own, but I've just flagged it for a moderator's attention to do so for me. Thank you again. | |
