A 50 mm diameter steel pipe is covered with 42 mm thick layer of material A with (KA = 0.07 W/mK) which is in turn covered with an insulation (kB= 0.048 W/mK) of 24 mm thick. the temperature of the steel air outside is 305 K and the outer surface of the insulation material is 370 K. -Calculate the heat transfer rate across the pipe wall -Calculate the interfacial temperature between material A and the insulation B.
