How much fuel (kerosene) does a 747 burn?

Another B747-400 estimate: 870,000 lbs accelerating at 9.1ft/s² is roughly 70,000 HP on takeoff estimating the weight and acceleration of the beast. There was a Top Fuel drag spreadsheet that was posted in 2014 that claimed "You get about 115 horsepower for each gpm (gallons per minute) of 90 percent nitro you burn" and if you factor in the 10,100 HP the graph was based on and the ~3.7 sec run it was looking at...you get 87.82 GPM or 1.46 gallon per second...BUSTED! Sure the Antron Browns car burns more fuel per second (all 4 of them), but it aint making 70,000 horsepower either. OK, bedtime......
