Consider one-dimensional conduction in a plane composite wall. the outer surfaces are exposed to a fluid at 25 c and a convection heat transfer coefficient of 1000 w/m2 k. the middle wall b experiences uniform heat generation q . b, while there is no generation in walls a and c. the temperatures at the interfaces are t1 261 c and t2 211 c. (a) assuming negligible contact resistance at the interfaces, determine the volumetric heat generation q . b and the thermal conductivity kb. la
