Question:
Consider a 20-cm-thick large concrete plane wall (k = 0.77 W/m · K) subjected to convection on both sides with T∞1 = 22°C and h1 = 8 W/m2 K on the inside, and T∞2 = 8°C and h2 = 12 W/m2 · K on the outside. Assuming constant thermal conductivity with no heat generation and negligible radiation.
(a) express the differential equations 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,
(c) evaluate the temperatures at the inner and outer surfaces of the wall.
