# Consider a large plane wall of thickness L 04 m thermal conductivity k 18 WmK and surface area A 30 m2 The left side of the wall is maintained at a constant temperature of

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.
