Calculate the heat transfer rate when a steel pipe conveying steam is insulated. The pipe has an inside diameter of 20 cm, and outside diameter 30 cm. The lagging is 10 cm thick and has a thermal conductivity ki of 0.1 W/m K. The thermal conductivity of the pipe wall kp is 80 W/m K, with inner face temperature of 200oC and outer insulated surface is at 20oC.
