Question
Three identical rods are welded together to form a Y-shaped figure. The cross-sectional area of each rod is A, and they have length L and thermal conductivity K. (Figure 1) The free end of rod 1 is maintained at T1 and the free ends of rods 2 and 3 are maintained at T0 a lower temperature . You may assume that there is no heat loss from the surfaces of the rods. ________________________________________________________________________________________________ What is the heat current in rod 1? Express the heat current in terms of any or all of K ,L ,A , and the temperatures T1 and T0
Explanation / Answer
H1=(2kA/3L)(T1-T0)
H2=(kA/3L)(T1-T0)
