Chapter 2
Heat Conduction Equation
2124E
A large plane wall is subjected to a specified temperature on the left (inner) surface and heat loss
by radiation to space on the right (outer) surface. The temperature of the right surface of the wall and the
rate of heat transfer are to be determined when steady operating conditions are reached.
Assumptions
1
Steady operating conditions are reached.
2
Heat transfer is onedimensional since the wall
is large relative to its thickness, and the thermal conditions on both sides of the wall are uniform.
3
Thermal properties are constant.
4
There is no heat generation in the wall.

Analysis
In steady operation, heat conduction through the wall must
be equal to net heat transfer from the outer surface. Therefore, taking
