Consider a 20-cm-thick large concrete plane wall (k = 0.77 W/mK) subjected to convection on both sides with T₁ = 27 C^o and h₁ = 5 W/m²K on the inside, and T₂ = 8 C^o and h₂ = 12 W/mK on the outside. Assuming constant thermal conductivity with no heat generation and negligible radiation:

(a) Express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the wall,

(b) Obtain a relation for the variation of temperature in the wall by solving the differential equation.
