The Alaska Pipeline carries 2 million barrels per day of crude oil 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 sheeting. Approximately half of the pipeline length is above ground, nominally running in the north-south direction. The insulation maintains the outer surface of the steel sheeting 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.GIVENFiberglass insulated pipe with air flow at 45? to its axisInsulation is covered with sheet steelLength of pipe above ground (L) = (800 miles)/2 = 400 milesPipe diameter (Dp) = 48 in.Insulation thickness (t) = 4 in.Sheet steel temperature (Ts) = 10?CAverage ambient air temperature (T??) = 0?CAverage air velocity (U??) = 2 m/sASSUMPTIONSThermal resistance of the sheet steel as well as contact resistance can beneglected
