PMAX - Pi EXP[ (3yZ pMAX /100) - 1] (E4) 



Setting p. = 1 atmosphere (1.014 x 10 pascals) and 



Z™,,^, = 125 (50% kill value—Equation 3.2.1) we get 

 PMAX 



PMAX =19.2 MPa (=2790 psi) (E5) 



(approximately 24 charge diameters) 



for the overpressure level PMAX corresponding to 50% kill 

 by this mechanism to fish which are very close to the water 

 surface .
