The diagram below illustrates a simplified version of the Jet Propulsion Laboratory's 25-ft space simulator chamber. Within it, tests are run for deep space probes and their components. In this particular experiment, a sensor assembly with its housing is placed inside. The sensor-housing electronics create heat such that q=3181.0 W exits the assembly's top surface into the chamber. The chamber itself is under vacuum, and its walls are at cryogenic temperatures to simulate conditions in space. Surfaces 1 and 2 are flat. Assume they are flush. The top surface of the chamber, Surface 4, can be approximated as a perfectly insulated, flat ceiling. The exposed surface of the floor, Surface 2, is a black, donut- shaped surface. Additional surface information can be seen below, including various parameters and dimensions. Assume all surfaces are opaque and diffuse, and conditions are at steady-state.

A thin outer border of a building's area covers 10×10m^2. The sky temperature is 300K meanwhile the temperature of the sun is 5800K. The overall distance between the sun and earth is 1.5×10^11 meters and the overall sun diameter is 1.4×10^9 meter and the earth diameter is 1.3×10^7 meters. The properties of the outer border are: ελ = 0.5 for λ > 6 µm & ελ = 0.1 for λ < 6 µm. The outer border can be considered a diffuse surface. Air current flows over the border with a velocity of 10 meters/second with a temperature of 300K. Beneath the border, the air inside the building flows over the bottom side of the border at 1 meter/second. Determine the steady-state temperature of the border for these conditions.
