Hello folks, I need help from an materials engineer or someone who knows about the materials strength laws. I first tried to make a rocket powered with rocket fuel, but this forum can't help-me with it cause I'm not american, and no one sends rocket motors international, so I am giving up with this fuel, but not with the Idea (I forgot to say that potassium nitrate is forbidden to buy in my country Brazil). I am making a high power water rocket, and its tank will be fueled with water and compressed air at 450-550psi. The tank will be 1,65m long and 70mm diameter. One observation is that its the ends will be capped with domed covers, welded to the tube (also made of aluminum) just like a propane tank. Now what I need help with : how can I calculate the needed wall thickness to resist 550 psi ? Thanks for attention
