Calculating the Stored Energy of a Pressurized Gas Vessel


When a gas is compressed, it stores energy.  If an uncontrolled energy release occurs, it may cause injury or damage.  Stored energies in excess of 100 kJ are considered highly hazardous. Sometimes it is helpful to think of stored energy in terms of grams of TNT. One gram of TNT contains 4.62 kJ of energy.
