The question is: What is the maximum amount of air that can pass through a hole 1 mm in diameter?
I'm trying to do hockey table yourself. Firstly, I am trying to understand how many fans I need to push the air uniformly. I'm thinking of doing good holes 1 mm in diameter or 1 / 2 mm. I also believe that questions of how much volume is in the box and how many holes there are (obviously). Can someone tell me a formula to calculate this?
7PSI x amount of gray in the table – the amount of floor + roof-PI
