Find the rate of heat flow through a cross section of the rod shown in figure(θ₂ > θ₁). Thermal conductivity of the material of the rod is K Which of the following gives the correct final result?

Question

G1 Physics · Accepted Answer

In steady conduction, heat current is H=kAΔT/L. Treat each segment as a thermal resistance Rₜₕ=L/(kA); series resistances add and parallel heat currents add. Evaluating the given data/statements gives Kπr₁r₂(θ₂-θ₁)/L. Therefore the correct answer is A.
