Using the apparatus used in the conduction of gases and liquids experiment to measure the thermal conductivity for air. When the power was 15 W the T1 and 72 w 97°C and 23°C. respectively. Knowing that the inner and outer diameters of the radial gap are 5.4 and 6.6 cm, respectively, and the surface area for the heat transfer is around 0.033 m², the thermal conductivity (W/m.K) for air is around: K- War AAT
