The Alaska pipeline carries 2 million barrels of crude oil per day from Prudhoe Bay to Valdez, covering a distance of 800 miles. The pipe diameter is 48 in., and it is insulated with 4 in. of fiberglass covered with steel sheathing. Approximately half of the pipeline length is above ground, running nominally in the north-south direction. The insulation maintains the outer surface of the steel sheathing at approximately 10°C. If the ambient temperature averages 0°C and prevailing winds are 2 m/s from the northeast, estimate the total rate of heat loss from the above-ground portion of the pipeline.
