A long cylindrical rod of diameter 100 mm with thermal conductivity of 0.5 W/m-K experiences uniform volumetric heat generation of 3.7 x 10* W/m³. The rod is encapsulated by a circular sleeve having an outer diameter of 400 mm and a thermal conductivity of 4W/m-K. The outer surface of the sleeve is exposed to cross flow of air at 27°C with a convection coefficient of 25 W/m2.K. (a) Find the temperature at the interface between the rod and sleeve and on the outer surface. (b) What is the temperature at the center of the rod? (a) Tinterface Touter (b) T(0) =
