Calculate the fragment hits per square foot

of target surface.

 

(Number of fragments  / (Drad)2 ) x 12.57) = hits p.sq.foot

 

Assumed warhead-fragments:  19 000

(19000 / (352ft x 12.57)) = (19000 / (1225 x 12.57)) = 1.2 fragments hits per sq foot 

or

1.2 x 10.8 = 12.96 fragment hits per sqm (square meter)

Where: 10.8 is the conversion factor from foot to sq. m

For a calculated  IEB

43.3 yards (IEB) x 3 = 129.9 foot (conversion from yard to foot)

19000 / 129.92 x 12.57 = 19000 / (16874 x 12.57) = 0.09 hits per square foot

or

(0.09 x 10.8) = 1 fragment hit per sq. m of target surface
