The detonation velocity values presented here are typically for the highest practical density which maximizes achievable detonation velocity. [ 1 ] The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the ...
The average means to average over the kinetic energy of all the particles in a system. If the velocities of a group of electrons , e.g., in a plasma , follow a Maxwell–Boltzmann distribution , then the electron temperature is defined as the temperature of that distribution.

The average free time of flight of a carrier and therefore the relaxation time is inversely proportional to the scattering probability. [15] [16] [18] For example, lattice scattering alters the average electron velocity (in the electric-field direction), which in turn alters the tendency to scatter off impurities. There are more complicated ...

CRC cites American Institute of Physics Handbook (AIPH) table 3f-2 for this value, but in AIPH table 2f-6 there are elastic constants reported that yield 3700,1570, 2620 WEL: 2680: AIPH: 3700: 1570: 2620: Table 2f-6. Calculated from Young's modulus of 147 GPa (lower than commonly accepted for Platinum), Poisson's ratio of 0.39, density of 21370 ...
A molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged. The typical vibrational frequencies range from less than 10 13 Hz to approximately 10 14 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm −1 and wavelengths of approximately 30 to 3 μm.
where D is the diffusivity of A through B, proportional to the average molecular velocity and, therefore dependent on the temperature and pressure of gases. The rate of diffusion N A is usually expressed as the number of moles diffusing across unit area in unit time. As with the basic equation of heat transfer, this indicates that the rate of ...
