A uniform copper bar 50 cm long is insulated on the sides and has its ends exposed to ice and steam respectively. If there is a layer of water 0.1 mm thick at each end, calculate the temperature gradient in the bar at steady state.
Thermal conductivity of copper = 1.04 cgs units
Thermal conductivity of water = 0.0014 cgs units.
Heat conducted through the film of water at the hot end is equal to the heat conducted through the copper bar.
Let Q be the heat conducted per second
Q = 0.0014 x A x (100 - t1) for ...
