Question

A uniform steel rod of length $50 c m$ is insulated on its sides. There is a layer of water of thickness $0.2 m m$ at each end of the rod. If the ends of the rod are exposed to ice of $0^{\circ} C$ and steam at $100^{\circ} C$ . Calculate the temperature gradient in the rod. Thermal conductivities of steel and water are $0.11 c a l - c m^{- 1} s^{- 1} (^{\circ} C)^{- 1}$ and $1.5 c a l - c m^{- 1} s^{- 1} (^{\circ} C)^{- 1}$ .
