1. A very long electrical conductor 10 mm in diameter is concentric with a cooled cylindrical tube 50 mm in diameter whose surface is diffuse and gray with an emissivity of 0.9 and temperature of 27°C. The electrical conductor has a diffuse, gray surface with an emissivity of 0.6 and is dissipating 6.0 W per meter of length. Assuming that the space between the two surfaces is evacuated, calculate the surface temperature of the conductor.

2. Liquid oxygen is stored in a thin-walled, spherical container 0.8 m in diameter, which is enclosed within where q12,N and q12,0 represent the radiation heat trans- fer rates for N shields and no shields, respectively.
