Aluminum tank gauge thickness
Greetings,
I live in an area where new construction requires some kind of water tank for fire truck access, I will also be using it for an exercise tank, 7 feet deep, (In order to kill 2 birds with one stone), it needs to be at least 3,000 gallons, I will figure out the diameter later. I would like o build it out of 6061 Aluminum. The head of water pressure is around 3 psi. for static water. I saw that dynamic was different. Given the exercise activity in the tank what gauge of Aluminum sheet should I use?
Thanks for any and all responses.
