A pipe (k=62 W/moC) having a inner diameter of 145 mm and outerdiameter of 160 mm is covered with two layers of insulation ofthickness 25.5 mm and 47 mm respectively and thermal conductivities0.15 W/moC and 0.07 W/moC respectively. The temperature of innersurface of pipe is 325oC and that of outer surface of theinsulation layer is 36oC. Determine the heat lost per meter oflength and interface temperature. Take the temperature of outersurface of the insulation layer as 50
