Question:

A spherical communications satellite 2 m in diameter is placed in orbit around the earth. The satellite generates 1000 W of internal power from a small nuclear generator. If the surface of the satellite has an emittance of 0.3 and is shaded from solar radiation by the earth, estimate the surface temperature.GIVENSpherical satelliteDiameter (D) = 2 mHeat generation = 1000 WEmittance (ε) = 0.3ASSUMPTIONSThe satellite radiates to space which behaves as a blackbody enclosure at 0 KThe system is in steadystate
