Help with problem, comparison of energy released

  1. Feb 5, 2010 #1
    Using the equation Force = Pressure x Area. How much energy would be released from an iron tube 48” long with an inside diameter of 2.1” and outside diameter of 3”. Wall thickness would be .9”. With 8500psi inside. Maybe I calculated it wrong but I got 1.1 million pounds of force released. Once I get the correct answer (hopefully you guys can help), I’ve been looking for a comparison to let people understand how much force that really is. For example, ‘x’ amount of force would equal 3.5lbs of C-4 detonation or a 7 ton truck falling off a seven story building. Something similar to that so it can catch a reader’s attention. Any help or ideas would be greatly appreciated. I’ve spent a few hours surfing google with no luck. Thanks!
