A spherical container of negligible thickness holding a hot fluid at 1400 and having an outer diameter of 0.4 m is insulated with three layers of each 50 mm thick insulation of k1 = 0.02: k2 = 0.06 and k3 = 0.16 W/mK. (Starting from inside). The outside surface temperature is 300C. Determine (i) the heat loss, and (ii) Interface temperatures of insulating layers.
