A uniform steel rod of length 50 cm is insulated on its sides. There is a layer of water of thick ness 0.2 mm at each end of the rod. If the ends of the rod are exposed to ice at `0^(@)C`, and steam at `100^(@)C,` calculate the temperature gradient in the rod. Thermal conductivities of steel and water are `0.11calcm^(-1)s^(-1)``""^(@)C^(-1) and 1.5xx10^(-3)calcm^(-1)s^(-1)``""^(@)C^(-1)`

Answer

`0.944^(@)C` per cm
