e- gas

### Information

Notes:

- The specific mass (m) is also 2kA/d, where kA (in the Units package) is the magnetic force constant and d (in this package) is the specific classical diameter of an electron, α3/(2π R∞ q).
- McBride and Gordon [McBride1996] provide correlations for the transport properties of e- gas. However, they are not entered here, since they contain only one temperature range (2000 to 5000 K) which is beyond the expected operating range of the model.
- The equation for the radius is the classical radius of an electron (see http://en.wikipedia.org/wiki/Classical_electron_radius).
- McBride and Gordon [McBride1996] provide correlations for the transport properties of e- gas. However, they are not entered here, since they contain only one temperature range (2000 to 5000 K) which is beyond the expected operating range of the model.
- The thermodynamic data [McBride2002] splits the correlations into three temperature ranges, but the coefficients are the same for each. Therefore, the temperature limits are set here such that the entire range is handled without switching. The lower temperature limit in the source data is 298.150 K, but here it is expanded down to 200 K. The constants are independent of temperature anyway.
