The air inside a chamber at T,i = 50 C is heated convectively with hi = 20 W/m2.K by a 200-mm thick wall having a thermal conductivity of 4 W/m.K and a uniform heat generation of 1000 W/m3. To prevent any heat generated within the wall from being lost to the outside of the chamber at T,o = 25 C with ho = 5 W/m2.K, a very thin electrical strip heater is placed on the outer wall to provide a uniform heat flux, qo" .

a) Determine the temperature at the inside wall surface (x = L) in C.

b) Determine the value of qo" that must be supplied by the strip heater so that all heat generated within the wall is transferred to the inside of the chamber.
