One experimental method of measuring an insulating
Chapter 17, Problem 106P(choose chapter or problem)
One experimental method of measuring an insulating material’s thermal conductivity is to construct a box of the material and measure the power input to an electric heater inside the box that maintains the interior at a measured temperature above the outside surface. Suppose that in such an apparatus a power input of 180 W is required to keep the interior surface of the box 65.0 Co (about 120 Fo) above the temperature of the outer sur-face. The total area of the box is 2.18 m2, and the wall thickness is 3.90 cm. Find the thermal conductivity of the material in SI units.
