The air inside a chamber at 54 C is heated convectively with heat transfer coefficient of 35 W/m2*K by a 0.29-m thick wall having a thermal conductivity of 6 W/m*K and a uniform heat generation of 1,700 W/m3. To prevent any heat generated within the wall from being lost to the outside of the chamber at 15 C with an outside heat transfer coefficient of 22 W/m2*K, a very thin electrical strip heater is placed on the outer wall to provide a uniform heat flux. (a) Determine the value of heat flux that must be supplied by the strip heater so that all heat generated within the wall is transferred to the inside of the chamber, (b) If the heat generation in the wall were switched off while the heat flux to the strip heater remained constant, what would be the steady-state temperature, T(0), of the outer wall surface?
