Valve, Gas fluid flow question

  1. Jun 22, 2010 #1
    Hi all,
    I am new here and need your help.
    After sudden opening of a ball valve with cross section area of 10 mm come to an blow up (explosion) of the 2" pipe.
    (before opening) Up stream the valve was the gas pressure 190 bar during downstream the pressure was 0 bar, however it was air inside (s.attached).

    Downstream of the valve the distance to the orifice plate is 1,5 m, there was upstream the OR an blow up of the pipe about 50%.
    Could you explain me the physical phenomenon, mathematical equation would be appreciated.
    best regards
