2) Consider a large plane wall of thickness L=0.4 m, thermal conductivity k=1.8 W/m.K, and surface area A=30 m². The left side of the wall is maintained at a constant temperature of T₁ = 90°C while the right side loses heat by convection to the surrounding air at T∞ = 25°C with a heat transfer coefficient of h=24 W/m².K. Assuming constant thermal conductivity and no heat generation in the wall, (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, and (c) evaluate the rate of heat transfer through the wall.
