Formulas and Key Relations

2. Conduction and Thermal Conductivity

Q = K A (θ1 - θ2) t / l

dQ/dt = -K A dθ/dx

3. Composite Slabs: Series and Parallel

θ = (K1 θ1 l2 + K2 θ2 l1) / (K1 l2 + K2 l1)

H = K1 K2 A (θ1 - θ2) / (K1 l2 + K2 l1)

H = A (θ1 - θ2) / (l1/K1 + l2/K2)

K = (l1 + l2) / (l1/K1 + l2/K2)

4. Searle's Method and Conductivity Measurement

K = m c (θ4 - θ3) l / [A (θ1 - θ2) t]
