The length of the copper rod is $\"\"$ .

\

The diameter of the copper rod is $\"\"$ .

\

The one end is kept at $\"\"$ .

\

The othe end of the copper rod is immersed in water at $\"\"$ .

\

Find the heat conduction rate along the rod.

\

The rate of conduction is $\"\"$ , where $\"\"$ is the thermal conductivity of the material, $\"\"$ is the cross section area, $\"\"$ is the higher temperature, $\"\"$ is the cooler temperature and $\"\"$ is the distance between two ends.

\

Thermal conductivity of copper is $\"\"$ .

\

Assume that the rod has uniform thickness.

\

The cross sectional area of the rod is $\"\"$ .

\

Substitute $\"\"$ .
