Question

4) Consider one-dimensional conduction in a plane composite wall.  The outer surfaces are exposed to a fluid at 25oC and a convection heat transfer coefficient of 1000 W/m2K.  The middle wall B experiences uniform heat generation  while there is no generation in walls A and C.  The temperatures at the interfaces are T1 = 261oC and T2 = 211oC.

 

  1. a) Assuming negligible contact resistance at the interfaces, determine the volumetric heat generation and the thermal conductivity kB.
  2. b) Plot the temperature distribution.
