Two bars of equal length and area have conductivities $2 k$ and $k$ and are joined end to end. The free end of the first is at $10 0^{\circ}$ C and that of the second is at $1 0^{\circ}$ C. Find the junction temperature in $^{\circ}$ C.

Answer:

Solution:

$2 k (100 - T_{j}) = k (T_{j} - 10)$ . So $200 - 2 T_{j} = T_{j} - 10$ and $T_{j} = 7 0^{\circ}$ C.
