The diameter of the Deep Water Horizon oil pipe is 21 inches.The oil stream emanating from the pipe exits at about 21 inches per second. 12 x 12 x 12 = 1728 cubic inches = 1 cubic foot.To find the cross-section of the pipe, you need to know that the area of a circle is: A = Ïr^2Calculate the circular cross-section of the Deep Water Horizon pipe: ______________________ (note: your answer is in sq. in.)Calculate the volume of oil exiting the pipe every second: ______________ cubic inches/second (hint: this involves multiplying a linear rate of inches per second with the cross section)Calculate the volume of oil exiting the pipe every minute: ____________________ cu. in/minutCalculate the volume of oil exiting the pipe every hour: _______________________ cu. in/hourCalculate the volume of oil exiting the pipe every day: __________________________ cu in/dayConvert cu in/day to cubic feet per day: ______________________________________ cu ft/dayConvert cu ft/day to barrels/day (5.61 cu ft/barrel of oil): _________________________ bbl/day (Note: bbl is the abbreviation for âbarrelsâ)Multiply bbl/day x 86 days: _________________________________= total barrels of oil leaked.Calculate the gallons of oil leaked: ___________________________= total gallons of oil leaked.(There are 42 U.S. gallons in a barrel of oil.)
