Problem 7: In an orbiting space station, an electronic package is housed in a compartiment
having surface area A, = Im which is exposed to space. Under normal operating conditions,
the electronics dissipate 1 kW, all of which must be transferred from the exposed surface to
space. If the surface emissivity is 1.0 and the surface is not exposed to the sun, what is its
steady- state temperature? If the surface is exposed to a solar flux of 750W/m and its
absorptivity to solar radiation is 0.25, what is its steady -state temperature?
