Consider heat generation in a slab of width 2b. The surfaces of the slab at y=+/b are at a reference temperature of 0 , the heat generation per unit volume is S, and the thermal conductivity is k. What is the heat flux at y=b ? Sb2/k 0.5Sb2/k 0.5Sb There is insufficient information to answer the question. Sb For the problem in question 2 , how much hotter is the temperature at the centerline y=0 than that at the wall? Sb There is insufficient information to answer the question. 0.5Sb 0.5Sb2/k 0.25Sb2/k For the slab in question 2 , what is the ratio of the centerline temperature to the average temperature in the slab? 1 There is insufficient information to answer the question. 3/2 2
