According to the far-field airblast approach, the overpressure depends on the weight of charge which is different than what we know in the explosives/shock physics during the explosives detonation (CJ pressure is constant in any charge size). Explain why it occurs.
in the far field airblast aproach we need a soil overburdon in term of mmass while in case of general physics of shock the only significance is of the charge .
