Even though heat is not a fluid, Eq. (14-11) has a close analogy in Poiseuille's law, which describes the viscous flow of a fluid through a pipe.
In Eq 14.11

(a) Explain the analogy.
(b) For two or more thermal
Conductors in series, the total thermal resistance is just the sum of the thermal resistances [Eq. (14-13)], Is the total fluid flow resistance for two or more pipes in series equal to the sum of the resistances? Explain.
In Eq 14.13
