🎓 Learning Paths

• Fourier's Law: $q_x = -kA \frac{dT}{dx} \to R = \frac{L}{kA}$
• Radial Flow: $R_{cyl} = \frac{\ln(r_2/r_1)}{2\pi k L} \to r_{crit} = \frac{k}{h}$
• Fins: $m = \sqrt{\frac{hP}{kA_c}} \to \eta_f = \frac{\tanh(mL_c)}{mL_c}$
• Transient: $Bi = \frac{hL_c}{k} < 0.1 \to \text{Lumped } \theta(t)$

• 1D Plane Wall: $Q = \frac{T_1 - T_2}{\sum L_i/(k_i A)}$
• Multilayer Cylinder: $R_{cyl} = \frac{\ln(r_o/r_i)}{2\pi k L}$
• Critical Radius: $r_{cr,cyl} = \frac{k}{h}, \quad r_{cr,sph} = \frac{2k}{h}$
• Rectangular Fin: $q_f = \sqrt{h P k A_c}\theta_b \tanh(mL)$
• Lumped Response: $\frac{T(t) - T_\infty}{T_i - T_\infty} = \exp\left(-\frac{t}{\tau}\right)$
