Easy way to find the potential energy in compressed air

  1. Feb 7, 2015 #1
    I have a .81 Cu. Ft. cylinder which is at a static pressure of 80 Psi. What is the easiest way to calculate the Potential Energy of the compressed air?

    Hi and welcome to PF.
    You would need to specify the conditions how the work is obtained from the compressed air because the conditions for the expansion will make a difference. Is it Isothermal or Adiabatic expansion?
    Is this basically a question about the possible energy in an explosion, if the cylinder ruptures, for instance? A bit more context would help to get the answer you need.
