HWC3-1) If the present pumping rate of crude oil through the Alaska pipeline with an ID of 48 inches is 500,000 barrels a day ( 1 barrel =42 US gallons) a) Is this turbulent flow? b) What would be the maximum rate of flow (barrels per day) if the flow were constrained to be laminar. (There are lots of complicating circumstances in the operation of the pipeline-for simplicity, assume the flowrate is steady with a dynamic viscosity of 0.025 lbs/ft2 and density of 1.8slug/ft3.) Ans: Laminar, 1.41106 barrel/day
