Dear Wolfram community,
a question on the definition of the quantity ‘ThermalConductivityCoefficient’ in the StandardAtmosphere Package:
Provided that ‘ThermalConductivityCoefficient’ stands for the thermal conductivity lam acc. to Fourier’s law of heat conduction
q = -lam grad(T),
then lam should be in the order of 0.025 W/(m K) for ambient air.
However, the command in the attached file yields a value of
0.000025362 J / (m s K) for condition at sea level (0 Meters).
This seems to be too low by an order of 3 magnitudes.
Is this quantity based on a different definition, other than assumed above ?
I am using Version 11.3.0.0.
