A new material has a measured thermal conductivity k of 200 BTU-in/hr-ft2 -°F. Is this material a thermal insulator or a conductor? Calculate the R and U values for a block of this material that is 3 inches thick. Now sandwich this block of material between two sheets of R-0.8 fiberboard. What is the new effective U value?

The thermal conductivity of an insulating material used over a hot pipe varies as k = 0.0545 (1 + 28.4 × 10–4 T) where T is in °C and k is in W/mK. This insulation is used for a thickness of 12 cm over a pipe of diameter 0.6 m. The pipe surface is at 300°C and the outside insulation temperature is 60°C. Determine the heat flow for a length of 5 m. Also find the mid layer temperature.

An experimental arrangement for measuring the thermal conductivity of solid materials involves the use of two long rods that are equivalent in every respect, except that one is fabricated from a standard material of known thermal conductivity kA while the other is fabricated from the material whose thermal conductivity kB is desired. Both rods are attached at one end to a heat source of fixed temperature Tb, are exposed to a fluid of temperature T∞, and are instrumented with thermocouples...

A solid surface is in diffusive and thermal equilibrium with a monatomic ideal gas at temperature t and chemical potential μ. An adsorption site on the solid surface can be either empty (energy ε0 = 0), singly occupied (ε1 = ε), or doubly occupied (ε2 = 2ε) by an atom from the gas. If two atoms adsorb onto the same site, they also interact by a vibrational mode of frequency w. Thus, the energy of a doubly occupied site can...
