Asteel pipe (k=45.0 w/m-k) having a 5.0 cm o. d. is covered with a 4.2 cm thick layer of magnesia (k=0.07 w/m-k) which is in turn covered with a 2.4 cm layer of fiberglass insulation ((k= 0.048 w/m-k). the pipe wall outside temperature is 370k and the outside surface temperature of the fiber galss is 305k. what is the interfacial temperature between the magnesia and the fiberglass?
