A plane wall of thickness 0.1 m and thermal conductivity of 25 W/mL.
The volumetric heat generation of the wall = 0.3 MW/m^3.
The wall is well insulated on one side while the other side is exposed to a fluid at 92 degrees Celsius with a convection heat transfer coefficient of h=500 W/m^2.
What is the maximum temperature in the wall?
