How much fuel can a passenger jet burn?
Yes about 1 gallon a second. Howards initial figures are correct 63000 gal, 8000miles equates to about 8 gallons per mile. but the rest is wrong. 8gal/mile x 600miles/hour = 48gallons/hour divide that by 60, 80gallons per minute, divide that by 60 = 1.3gallons per sec. This is with max weight . With less weight and shorter flights, they will need less fuel and the plane will get better fuel economy. So 1 gallon a second is accurate. BTW a 747 APU burns about 2 gallons per minute. Using Wiki figures 514mph, 3500mile range, and 6875gallon capacity uses about 1/4 of a gallon per sec.
