17. A crude-oil pipe line is carrying 6000 bbl (42 gal each) of crude oil daily through 27 miles of single pipe, 12 in. ID. This capacity is now insufficient to meet the consumers' requirements. Accordingly, a parallel branch of the same size, extending for one-third of the total distance, is to be added. How much has the capacity of the pipe line been increased by the addition of the parallel branch if the line is level throughout, the oil has a specific gravity of 0.91 and a viscosity at flowing temperature of 500 centipoises, and the same pressure is maintained at the inlet to the pipe line
