Steady State Temperature Conduction
Three conductions of same length having thermal conductivity k
1, k
2 and k
3 are connected as shown in figure.

Area of cross sections of 1
st and 2
nd conductor are same and for 3
rd conductor it is double of the 1
st conductor. The temperatures are given in the figure. In steady state condition, the value of θ is __________ °C.
