I work as a metal fabricator in a welding shop. Our safety committee wants everyone to volunteer and discuss safety under their own topic. I picked the discussing of oxy-acetylene torch and cylinders. I wanted to give the employees an idea of what would happen if a 2600 psi bottle blow up or...- cutinoak

Oxygen cylinder pressures
Say we have an oxygen cylinder 8"diameter 50" tall (not sure of the exact dimensions). The pressure inside is at 2600 psi. If I find the area of inside the tank 8 x pi x 50= 1256, do I take 1256sq" x 2600 psi to find the total amount of force exerted inside the tank as 3,265,600 lbs, or is it...- cutinoak
