The experiment utilizing Eq. 11.26 was conducted due to Ingen-Hausz. In this experiment, thermal conductivities of different materials are compared and determined if that of any one material is known.
Here, several rods of different metals and of equal area of cross section and polish to ensure equal emissivity are coated with wax. One end of each of the rods is placed in an oil bath as shown in Fig. 11.3.
Fig. 11.3 Ingen Hausz's experiment
Heat is transferred from the end introduced into the bath towards the other end exposed outside. This causes melting of wax on the surface. At first, heat is transferred quickly ...
