Vertical Rise H of a Gas Globe near the Surface 

 of the Sea and near a Vertical Wall 



The rise is from the time of detonation up to the time of the next peak recompression. R2 is the 

 intervening maximum radius. Curves are shown for A positions: (A) X = Z — ZR^i (B) X = 2R2, 

 Z = 3.5«2; (C) X = 3.5if2> 2 = 2«2; (D) X = 3.5«2> ^ = 3-5R2' "^^^^ •''^ is *^® distance of the point 

 of detonation below the surface and Z the distance of this point from the wall. W is the weight 

 of the chetrge in pounds. For R2 see Figure A or Equation [I8].
