I'm not really sure if this is the appropriate place to ask this and am not familiar with this forum so I apologize if I posted in the wrong place, but I would like some help. I need to compare the explosive force of a 12 gram CO2 canister(Like in BB Guns), a regular 275 gram aerosol can(such as air freshener or bug spray) both of which are pressurized and will rupture with heat(The force of that rupture, explosion basically, is what I need to figure out). Also for comparison I need to find out the explosive force of a legal(In any state), consumer available(no license required) firework - Preferably one small, like a bottle rocket(From Black Cat Fireworks website - "We load our rockets...with the maximum 130 milligrams of report powder", though I'm not sure it that's what's needed), and one large like multiple shot artillery shells/mortars. For the aerosol can and Co2 canister I need it as is, not emptied and filled with something else. The explosion would have to be the result of heat causing pressure to build until rupture. The fireworks would obviously be when it goes off. If given the formulas to calculate this for each and told what to plug in where I can do the exact math myself, but all help is appreciated. This information will be going toward a court case, and as such is not going to be tested physically, the numbers are all that are needed. I appreciate any help, thank you.
