The new Gulfstream 650 will use about 3,000 pounds of jet fuel per hour. That's just under 440 gallons an hour.

The 4-engined Boeing 747 burns about 25,000 lbs of fuel per hour on average.

747 running on GE engines can use up to 32000 lbs of fuel per hour on each engine at normal range of takeoff settings

initial climb speed of a 747 is 1800 to 2400 feet per minute depending on load

777's engines for some reason are more greedy at takeoff, maybe its the high bypass ratio, they use fuel at a rate of 50,000lbs per hour, max, at normal range of takeoff settings
