Examine the figures and the equations for calculating the temperature Tx at the boundary under steady-state heat transfer by conduction, Hot reservoir Gold reservoir k2A(TH - TX) KIA(Tx - To) RT R2 Pcond - L2 KIL2 To + k2LITH Figure 2 TX - KIL2 + k2L1 Figure 1 Now consider Figure 2, which is two rectangular rods R1 and R2 of equal length. The thermal conductivityes of R1 and R2 are 35 and 67 W/m.K respectively. If T2 = 117 C and T1 = 74 C, calculate the temperature at the boundary of R1 and R2
