Effective Thermal Conductivity of Pipe

[cbalsil]

I am using a specialized well bore anlysis program that calculates thermal profiles in down hole. The program requires a "k" thermal conductivity value for drill pipe as an input.

I am using a pipe that has insulation at different locations along its length. I would like to know how to calculate the effective "k" (thermal conductivity) of one pipe section "L". The pipe is basically steel with an insulation layer.

Interesting question. Did you mean to post it to the Aircraft engineering forum?

Remember, first define the problem, then solve it.

Is k for through the thickness or along the length?
