How much fuel does a rocket use?
462198
it depends on whattype of rocket. it also depends on what fuel that you use. and how high you want it to fly. whether you usea  solid or liquid propellent. how heavy your rocket and payload is. be more specific with this.

I'd just buy solid rocket fuel at hobby store. Blackpowder is just going to explode and really not burn.

A Jet engine sucks in air, compresses it and forces it out the back to produce thrust.\n\nA Rocket motor uses a chemical reaction of two substances in a sealed container to produce thrust.  When the container is opened the chemicals force their way out.\n\nImagine a bottle of lemonade.  Shake it up and the open the top.  That is your rocket motor.

iron would be much denser and would increase the weight load of the fuel, changing the power requirements for the rocket.  Also, iron tends to oxidize much faster.

There are too many variables to be able to accurately answer this question.  There are many different types of helicopters with different sizes of power plants.  External factors such as the load being carried, wind speed, etc. also contribute to how much fuel will be used.

You are using the term "power" incorrectly. Power is the rate of production of energy. A jet may have enough energy, but it does not have enough power. A fully fueled jet may be able to burn all it's fuel with oxygen from the surrounding atmosphere to generate enough energy to make it to orbit, but it takes many hours to do that, and all the time it is being slowed by friction with the atmosphere. The shuttle burns all it's fuel in 10 minutes, and it carries it's own oxygen in a tank so it can operate outside the atmosphere. So even though they may have similar energy, the shuttle has far more power.

The external tank on the space shuttle uses liquid Hydrogen and liquid Oxygen.  I hope that helps.

if you are using a gas engine... look into 0.21 litter 2 stroke nitro glow engines. they can reach around 2.5 hp. unfortunately, the 35% nitro fuel costs like $60 per gallon. however, you do get a ton of hours per gallon. they are nice because they produce 2.5 hp while fitting in the palm of your hand. a friend of mine has a car powered by a 0.15 litter engine that will reach about 50 mph on a level area.

engines for space craft don't need to constantly exert forward thrust to keep going, like airplanes. They need to to escape the earth's gravity, but once cleared, they can keep going on forward momentum, using brief propulsion to correct the course of the space craft. \n\nMars and the moon cannot use gasoline based craft, there's no oxygen to burn, so they likely need electric motors, maybe solar powered. Not exactly sure on this but I would say an electric motor of sorts.

A typical liquid engine uses hydrogen as fuel and oxygen as oxidant; a typical solid propellant is nitroglycerine. In the liquid engine, the fuel and oxidant are stored separately at extremely low temperatures; in the solid engine, the fuel and oxidant are intimately mixed and loaded directly into the combustion chamber. A solid engine requires an ignition system, as does a liquid engine if the propellants do not ignite spontaneously on contact.

A solid propellant rocket has a solid fuel core, for example gunpowder. A liquid propellant rocket, such as an ICBM, has liquid for fuel, like gas (but a specialized fuel more developed than gas).\n\nA rocket with solid fuel can only go a short distance. Liquid fuel is used more for missiles that have a long way to go and can be guided (intelligent).

a good resource:\nhttp://www.orbiterwiki.org/wiki/Main_Page\nit links to everywhere that is Orbiter related\n\nespecially useful one:\nhttp://www.orbiterwiki.org/wiki/Orbiter_tutorials\n\nTo launch rocket, just keep pressing + buttn for max power, or use the Ctrl+[+] to make the power increased slowly, and permanent. Then when the plane reaches a certain speed, press the down button.

The thrust of the burning gasses out of the rear of the rock causes a force against the rocket. If the resulting force is more than the force of gravity, the rocket accelerates according to the formula A= F/M. Where M= the mass of the rocket and F=the net force of the burning gasses minus the force of gravity. As the rock rises, it looses mass due expending its burnt fuel. That causes it to accelerate faster. Also as it rises, the force of gravity becomes less increasing the net force impelling the rocket, thus causing it to accelerate faster.

The Basics\nWhen most people think about motors or engines, they think about rotation. For example, a reciprocating gasoline engine in a car produces rotational energy to drive the wheels. An electric motor produces rotational energy to drive a fan or spin a disk. A steam engine is used to do the same thing, as is a steam turbine and most gas turbines.\n\nRocket engines are fundamentally different. Rocket engines are reaction engines. The basic principle driving a rocket engine is the famous Newtonian principle that "to every action there is an equal and opposite reaction." A rocket engine is throwing mass in one direction and benefiting from the reaction that occurs in the other direction as a result.\n\nA rocket engine is generally throwing mass in the form of a high-pressure gas. The engine throws the mass of gas out in one direction in order to get a reaction in the opposite direction. The mass comes from the weight of the fuel that the rocket engine burns. The burning process accelerates the mass of fuel so that it comes out of the rocket nozzle at high speed. The fact that the fuel turns from a solid or liquid into a gas when it burns does not change its mass. If you burn a pound of rocket fuel, a pound of exhaust comes out the nozzle in the form of a high-temperature, high-velocity gas. The form changes, but the mass does not. The burning process accelerates the mass.\n\nAnd that is how the rocket moves foward

You need to give more info, like fuel capacity, weight of rocket, length of fueled burst.

Rockets carry two components -- fuel to burn and their own oxidizer to enable that in the near-vacuum of space.  In the case of liquid fuels, the two components must be stored separately.  Some solid rocket propellants have the fuel and oxidizer mixed together.

There is about 20% oxygen in the air which is more than enough.\n\nAlthough a pound is 454 grams. you asked about gallons. Gasoline is about 6 pounds per gallon.\n\nMost gasoline is burned in internal combustion engines which do not burn it completely.It forms carbon monoxide.\n\nGasoline is not pure octane, C8H18 \n\n 2C8H18 + 25O2 ---> 16CO2 + 18H2O \n\nNow you can work out the rest, 2 moles of octane to 25 moles of O2. Use themolecular weight per mole of each.Figure out how many moles of octane yoy have.
