A large plane wall has a thickness of L=14 cm and thermal conductivity of k=191 W/(m°C). The left side of the wall (x=0) is well insulated while the right side loses heat by convection to the ambient air at To=16°C and h=39 W/(m²°C). Heat is generated in plane wall at a rate of g=a+bx (W/m³) where a=16,843 W/m and b=231 W/m4. Calculate the temperature of the wall at x=L by considering steady one-dimensional heat transfer and constant thermal conductivity.
