If I wanted to calculate how hot (worse case scenerio) a piece of metal just outside the earth's atmosphere would get due only to the sun's radiation I used:
q = sigma * emiss * (Tsun^4 - Tmetal^4) knowing q = 1367 W/m^2 Tsun - 6000K assuming emiss = 1 for black body I am getting a really hot piece of metal - 4236K did I miss something? |
