Thermal Conductivity Of Metals

The thermal conductivity of the tube material and the extended surface is needed for calculating the heat transfer coefficients. The conductivity of some of the popular materials can be described by the following curves.
Metal 1 Graph Metal 2 Graph Metal 3 Graph Metal 4 Graph
To make it easier to use when using a computer, we can fix a script to interpolate the curves for us as follows,
