VG 64: How does the concept of thermal resistance relate to the insulation properties of materials, and what factors influence thermal resistance behavior?
Added by Angela F.
Step 1
It is the reciprocal of thermal conductance and is typically denoted as R-value in building insulation. The higher the R-value, the better the insulation properties of the material. Show more…

The thermal conductivity of a wall can be modeled similar to an electric resistance, where q in the heat rate in W, T1,2 is the temperature on the sides of the wall in K, and Rth is the thermal resistance in K/W. A composite wall can be modeled as a system of thermal resistances in series, that is: Rtotal = R1 + R2 + R3 + ... Suppose that a composite wall is built with 4 layers of the same material that has a mean thermal resistance of 80 K/W with a standard deviation of 1 K/W. What will be the mean thermal resistance of the wall and the standard deviation of the mean?
