Emittance_CO2&H2O

The function emittance_CO2&H2O(p_w, p_c, p_tot, L, T_g) determines the emissivity of a carbon dioxide/water vapor mixture

where
  p_w - partial pressure of water vapor 
  p_c - partial pressure of carbon dioxide 
  p_tot - total pressure, including water vapor, carbon dioxide, and non-participating gases 
  L - radius of the hemisphere (also can be extended to surfaces other than a small surface element at the center of the hemisphere) 
  T_g - temperature of the all of the gases 

Example:

e=Emittance_CO2&H2O(p_w, p_c, p_tot, L, T_g)
p_w=0.01*Po#
p_c=0.0004*Po#
P_tot=Po#
L=10 [m]
T_g=1200 [K]

{Solution: e=0.137}
