# Question: a 40kmlong pipeline delivers petroleum at a rate of 4000...

###### Question details

A 40-km-long pipeline delivers petroleum at a rate of 4000 barrels per day. The resulting pressure drop is 3.45 x 106 Pa. If a parallel line of the same size is laid along the first 18 km of the line, what will be the new capacity of this network? Flow in both cases is laminar and the pressure drop remains 3.45 x 106 Pa. Express your answer of the new capacity in barrels per day (bbl/day). Interesting aside, a barrel is equivalent to 42 gallons or 159 liters. Comment on which case (extra pipe along first or last 18 km) is a better use of the company’s resources.
