Question

Radius of a conductor increases uniformly from left end to right end as shown in fig Material of the conductor is isotropic and its curved surface is thermally insulated from surrounding. Its ends are maintained at temperatures $T_{1}$ and $T_{2}(T_{1} > T_{2})$: If, in steady state, heat flow rate is equal to $H$, then which of the following graphs is correct

Dr. Abubacker · Accepted Answer

(b) 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
