A steam pipe line of 150/160 mm in diameter is covered with layer of heat insulating material of thickness 100 mm. Thermal conductivity of tube is 50 W/m deg C or kcal/m-hr-deg C and Ains,mat = 0.09 kcal/m- hr-deg C. Temperature of pipeline inside surface is 400 deg C and temperature of the outside surface of insulating surface is 50deg C. Find loss of heat from length of 1m of pipeline and temperature at interface of insulation.
