where n is the number of electrons per mole, μ0 is the vacuum permeability, e is the elementary charge, 〈r2〉 is the average square radius of the electron orbit, me is the electron mass, c is the speed of light in vacuum, and the negative sign reflects the repulsive tendency. While...
It is observed that the visible flame emission decreases with the increase of the mass fraction of water mist. Cao et al. [24] established a three-dimensional numerical model of methane explosion suppression by ultrafine water mist, and numerically studied the heat transfer process between ...
The density of the substance is the ratio between a specified mass of that substance and its corresponding volume. The density of a mass will work for any mass with a corresponding volume since density is specific to the substance in consideration. Densities have no unique unit ...
