A variety of corrections to the Mott–Gurney law along with new equations to account for disorder and impuri- state on the gulf of mexicoThe Gurney equations are a set of mathematical formulas used in explosives engineering to relate how fast an explosive will accelerate an adjacent layer of metal or other material when the explosive detonates. This determines how fast fragments are released by military explosives, how quickly shaped charge explosives accelerate their liners inwards, and in other calculations such as explosive welding where explosives force two metal sheets together and bond them. state one aim or objective of the unNettettraps are filled, the current is assumed to follow the Mott− Gurney law in the absence of trapping (4.
