Then you could divide the 12000 pounds by your weight calculation and come up with an answer. I would rather just figure about 6 pounds per gal times 100 gals per hour divided in to 12000 = about 20 mins. Who would you rather hire?

BTW a really experienced 727 Capt. would just say, "I'd get the flight engr. to figure that out!"
