12.3-2. Determination of Thermal Conductivity. In determining the thermal conductivity of an insulating material, the temperatures were measured on both sides of a flat slab of 25 mm of the material and were 318.4 and 303.2 K. The heat flux was measured as 35.1 W/m². 455 Calculate the thermal conductivity in btu/h · ft· °F and in W/m · K.
