Seven rods A, B, C, D, E, F and G are joined as shown in figure. All the rods have equal cross-sectional area A and length l . The thermal conductivities of the rods are K A = 2K C = 3K B = 6K D = K 0 . The rod E is kept at a constant temperature θ 1 and the rod G is kept at a constant temperature θ 2 (θ 2 > θ 1 ).
A
Show that the rod F has a uniform temperature θ = (3 θ 1 + θ 2 )/4.
B
Find the rate of heat flow from the source which maintains the temperature θ 2 .
