A 1 cm thick steel pipe, 1m long, with an internal diameter of 5 cm is covered with 4 cm thick insulation. The inside wall temperature of the steel pipe is 100°C. The ambient temperature around the insulated pipe is 20°C. The convective heat-transfer coeffi cient on the outer insulated surface is 50 W/(m 2 K). Calculate the temperature at the steel insulation interface. The thermal conductivity of steel is 54 W/(m K), and the thermal conductivity of insulation is 0.04 W/(m K).
