  We use an integral analysis of conservation equations of mass and energy, to
determine the drop size and distributions during shock-induced drop break-up.
The result is an updated form for the drop size as a function of its final
velocity, from a series of work applied to various atomization geometries.
Comparisons with experimental data demonstrate the validity and utility of this
method. The shock-induced drop size and distributions can be predicted within
reasonable accuracy as a function of the drop velocity ratio and fluid
properties. The result also illustrates the dynamical process of kinetic energy
deficit transferred to the surface tension energy, and the skewing of the drop
size distribution due to the non-linear dependence on velocity ratio.
