Q2) A constant heat flux (a -50 W/m2) is applied to a 1-D plane wall (k - 0.4 W/m K) on one side. The other side is subjected to convective boundary condition (h- 10 W/m? .K.Tm-25°C). A volumetric heat (q = 300 W/m*) is generated in the plane wall. If the plane wall has a thickness of L = 100 mm, a) Calculate surface temperatures T(x 0) and T(xL). b) Determine the location of the maximum temperature in the slab....
