Atmospheric pressure in convection calculation

[jakaortar]

Since not all people live at sea-level, it would be useful to include air-pressure (or air-density) correction factor to convective heat transfer calculation. It also affects evaporation but influence there is very very small.

The usual correction in literature is:
hc = hc_seaLevel * k
k being (pressureAtSite / pressureAtSeaLevel)**n

n ranges from
0.50 in Tikuisis 2004, https://www.researchgate.net/publication/235037111_Prediction_of_Times_of_Facial_and_Finger_Freezing_During_Cold_Air_Exposure
to
0.55 in Gagge 1977, https://www.researchgate.net/publication/229601121_Heat_Exchange_Between_Human_Skin_Surface_and_Thermal_Environment
to
~1.00 in MENEX-2005

I was to fast in writing that sentence - it seems it is not clear yet how big influence of air pressure on evaporative heat loss is.

Some sources say he = he_seaLevel * k
k being (pressureAtSeaLevel / pressureAtSite)**0.45

Other sources say influence is smaller.

Thank you for your suggestion.
I added the codes to correct hc and he values.
