They use bladders, and they're located in the wings.
Fuel on the 747 is stored mostly in the wings. There is a "center wing" tank that is actually underneath the cabin. Some models of the 747-400 also have fuel in the tail.
a 747 can fly 1,440 km
also the weight of 747 on a full tank
A Boeing 747 tanks capacity is 54,206 gallons, different models of aircraft would have a different tank capacity.
it is located in the wings of the aircraft. ALSO... http://www.boeing.com/commercial/747family/pf/pf_facts.html The 747-400 carries 3,300 gallons (12,490 L) of fuel in the horizontal (tail) stabilizer, allowing it to fly an additional 350 nautical miles
Fuel on a Boeing 747 is stored in multiple tanks located in the wings and the center fuselage. The wing tanks are the primary fuel reservoirs, while the center tank, located in the belly of the aircraft, provides additional capacity. This configuration allows for optimal weight distribution and balance during flight. Fuel is pumped from these tanks to the engines as needed.
The quick answer is 14.7psi. The fuel tanks are not pressurised and are vented to atmosphere. So the pressure inside the tank is whatever the ambient pressure outside the aircraft is. Hence the maximum pressure inside the tank will be ambient pressure at sea level, i.e. 14.7psi or thereabouts.
The 747-8l has a total fuel capacity of 64,225 U.S. gallons. Fuel is normally distributed across five separate tanks - two in each wing and one in the fuselage.
All 747's use Kerosene.
The 747-400ER can carry more than 63,500 gallons of fuel (240,370 L).
Not really, In current times, the 747-400 could fly the, about, 22 hour flight from Sydney to London flight if needed but there would be some changes to the flight. There would have to be a larger fuel tank added, no cargo and not a full load of passengers. In 1989, a Qantas 747-400 flew directly from Sydney, Australia, to London, England on its delivery flight. This aircraft was not carrying any passengers or cargo aboard. This 747 had a extended fuel tank installed so it could travel the entire distance with no stops.
The accepted average weight of Jet A fuel is 6.84 pounds per gallon based on specific gravity (but varies based on temperature, additives, etc.) The Boeing 747-400ER can carry more than 63,500 gallons of fuel which is about 434,340 pounds fuel load weight. Information provided by Jet Advisors
