A cylindricаl wаter heаting element cоnsists оf an inner rоd (k = 2 W/m-K, r = 6 mm) that produces heat, surrounded by a protective sheath of outer radius 9 mm and k = 25 W/m-K. There is no gap between the rod and the sheath. The outer surface temperature of the sheath is 500 K, and the water being heated is at 300 K, with h = 2000 W/m2-K. Calculate: a) The temperature at the inner surface of the sheath b) The temperature at the center of the heating element. (25 min, 35 points)
