Heat loss from an insulated pipe a standard schedule 40


Heat loss from an insulated pipe, a standard schedule 40, 2-in. steel pipe (inside diameter 2.067 in. and wall thickness 0.154 in.) carrying steam is insulated with 2 in. of 85% magnesia covered in turn with 2 in. of cork. Estimate the heat loss per hour per foot of pipe if the inner surface of the pipe is at 250F and the outer surface of the cork is at 90°F. The thermal conductivities (in Btu/hr. ft. F) of the substances concerned are: steel, 26.1; 85% magnesia, 0.04; cork, 0.03.
