Material of the conductor is isotropic and its curved surface is thermally isolated from surrounding. Its ends are maintained at temperatures T1 and T2 (T1 > T2): If, in steady state, heat flow rate is equal to H, then which of the following graphs is correct
A)
B)
C)
D)
Correct Answer: B
Solution :
Since the curved surface of the conductor is thermally insulated, therefore, in steady state, the rate of flow of heat at every section will be the same. Hence the curve between H and x will be straight line parallel to x-axis.
