Four identical rods
AB, CD ,CF and
DE are connected as shown in figure. The length, cross-sectional area and thermal conductivity of each rod are
L, A, K respectively. The ends
A, E, F are maintained at temperature
T1, T2 and
T3 respectively. Assuming no loss of heat to the atmosphere, calculate the temperature at
B [CB=BD].
(Consider
T3 as higher temperature)
