That is, the scaled parameters for cube root scaling are:
that is, pressure and velocity are the same for the prototype at homologous times.
Example 2
Use cube root scaling to compare the shock wave from a 300 kg explosive charge with
the shock wave from a 300 g charge of the same explosive type and shape.
that is, the same peak overpressure and shock wave velocity occurs at 100 m from the
300 kg charge as occurs at 10 m from the 300 g charge, but the +ve duration t and
d
impulse I are ten times greater.
