Log-Mean Area
We revisit the problem regarding heat transfer through a copper pipe.
Our focus is to reformulate the equations so we can employ the electrical circuits analogy to simplify the analysis!
NOTE: This is ONLY valid for steady state, constant thermal conductivity, and no heat generation/consumption!
