A cylindrical metallic shell has inner radius r, =2 cm and outer radius r, = 4 cm and it has a length L = 50 cm. The inner and outer surfaces are maintained at T, = 0°C and T, = 100°C. The thermal conductivity of metal is 69.3 Wm 'K. Find the rate of flow of heat from the outer to the inner surface.
