  2. Usable fuel - Wikipedia

    en.wikipedia.org/wiki/Usable_fuel

    Usable fuel is the total amount of fuel in an aircraft minus the fuel that cannot be fed into the engine(s): fuel under the pump-intake, fuel behind ribs of a tank, fuel in lines between the tanks and the engines etc. As this figure is calculated/defined for a plane in level flight it is possible that the engines of an aircraft run dry (out of ...

  3. Diesel fuel tanks in trucks - Wikipedia

    en.wikipedia.org/wiki/Diesel_fuel_tanks_in_trucks

    Replacing a cylindrical fuel tank with a D-Tank can result in 46% additional fuel capacity. When calculating volume requirements, one would begin by assessing the available space. Once length, width and height restrictions have been ascertained, the easiest method of determining volume is with the use of a truck tank volume calculator.

  4. Engine displacement - Wikipedia

    en.wikipedia.org/wiki/Engine_displacement

    Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed ) an engine might be capable of producing ...

  5. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    For energy storage, the energy density relates the stored energy to the volume of the storage equipment, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy.

  6. Fuel fraction - Wikipedia

    en.wikipedia.org/wiki/Fuel_fraction

    The fractional result of this mathematical division is often expressed as a percent. For aircraft with external drop tanks, the term internal fuel fraction is used to exclude the weight of external tanks and fuel. Fuel fraction is a key parameter in determining an aircraft's range, the distance it can fly without refueling.

  7. How to Calculate Gas Costs for Your Next Road Trip - AOL

    The higher the mpg, the more fuel-efficient your car is and the less money you’ll spend on gas during your road trip. Now, to calculate gas cost per mile simply divide the total miles driven by ...

  8. Fuel tank - Wikipedia

    en.wikipedia.org/wiki/Fuel_tank

    A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids, often gasoline or diesel fuel. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled ( fuel pump ) or released (pressurized gas) into an engine .

  9. Volumetric flow rate - Wikipedia

    en.wikipedia.org/wiki/Volumetric_flow_rate

    The area required to calculate the volumetric flow rate is real or imaginary, flat or curved, either as a cross-sectional area or a surface. The vector area is a combination of the magnitude of the area through which the volume passes through, A , and a unit vector normal to the area, n ^ {\displaystyle {\hat {\mathbf {n} }}} .
