The present pumping rate of crude oil through the Alaska Pipeline with an ID of 39 in is 550,000 barrels per day (1 barrel is 42 U. S. gallons). For crude oil at 60ºC, take ρ = 860 kg/m3 and μ ≈ 0.004 kg/m·s. What would be the maximum rate if the flow were constrained to be laminar? Take π = 22/7. Answer is asking for maximum flow rate for barrels per day
