Lean Burn = higher air-fuel ratio, Less power, more economical Rich Burn = lower air-fuel ratio, More power, less economical
Because the higher the altitude, the thinner the air, so the less work is needed by the engines. Sometimes there is also strong tailwinds which will speed it up. Also, this burns less fuel.
It is because the higher up the plane is, the lower the air pressure. When the air pressure is lower, there are less air molecules, resulting in less friction. Therefore it uses less fuel.
Higher is better.. Less fuel to spend and more fuel effeciency gets u further on less.
Heyy I'm dum
You will always burn your trout, but you will burn it less often when you get higher Cooking Level.
it depends, pilots fly airplanes at different altitudes depending on the weather systems around the area at the time. Most large aircraft or jumbo jets want to fly at altitudes exceeding 25,000 feet because at higher altitudes jumbo jets burn less fuel to go the same distance that it would take if it were flying at a lower altitude. I would estimate that passenger planes fly somewhere between 30,000 feet and 40,000 feet. Jumbo jets can't fly much higher because the air will become so thin that they can't climb and more. And much lower will require more fuel because the air is more dense.
Generally yes. There is less drag at higher altitudes, and thus better fuel economy, right up until the airplane can't get enough air to burn with with fuel to get the power needed to go faster and higher. Of course it takes extra fuel to get up there, so only long distance travel is done at high altitudes.
More massive stars have much higher temperatures and pressures. Although they have a lot more fuel, it is consumed at a much higher rate than lower mass stars. They burn very brightly and hot, but for less time. Lower mass stars have lower temperatures, but they have longer lives as they burn their fuel at a much lower rate.
Kerosene isn't. However, jet fuel, kerosene, and diesel fuel all are very similar. They're less refined than unleaded fuel, and that reduces the risk of on-board fires, for one. Additionally, they burn at a higher BTU rate than unleaded/petrol fuels.
Much more because massive stars are larger and need to burn of more fuel to survive.
SAVE FUEL 1) OIL WHICH BURNS NEVER RETURNS. 2) THE LESS YOU BURN ,THE MORE YOU EARN. By: SONALI MARTIN
It usually depends on the make. Higher end props tend to be safer than jets because of all the problems that might occur on sophosticated aircraft, such as Jets.
because it doesn't burn as much fuel.the less fuel burned ,the less emissions are emitted.
A 747 gets slightly less than 1 mile per gallon of jet fuel.
All aircraft, not just jets, have shapes as streamlined as possible to enable them to fly faster and use less fuel.
Because they do not burn as much fossil fuel.
With fire or flames, when the temperature reaches higher degrees it begins to burn white. Less "hot" flames will burn orange.
The suns mass. More massive stars have much higher temperatures and pressures. Although they have a lot more fuel (hydrogen), it is consumed at a much higher rate than lower mass stars. They burn very brightly and hot, but for less time.
Shorter. More massive stars have much higher temperatures and pressures. Although they have a lot more fuel, it is consumed at a much higher rate than lower mass stars. They burn very brightly and hot, but for less time.
The fuel burn of any aircraft varies according to aircraft configuration, type and number of engines, weight, altitude, etc., but a "rough" average hourly burn for "jumbo jets" (Large, heavy, four engines) would probably be in the 20,000 + lbs per hour range. (3000-3500 gal/hr) By contrast, a fuel efficient 767 with only two engines can burn in the range of 10,000 pounds per hour or less. A typical 5+30 flight from Seattle to Hawaii in a 767 will use around 50,000 pounds of fuel. (Jet fuel, depending on temperature, is usually calculated at about 6.7 pounds per gallon.)
American Airlines jets are more efficient as they have less paint. It takes 4 tonnes off the total weight of the jet.
they do that if it crashes or doesn't make a proper landing and if it catches fire there is no fuel to burn and there is a lot less chances of it blowing up

the mass decreases as the wax burns so it displaces less water
