2. Propelling nozzle - Wikipedia

   en.wikipedia.org/wiki/Propelling_nozzle

   The gas expands adiabatically with low losses and hence high efficiency. The gas accelerates to a final exit velocity which depends on the pressure and temperature at entry to the nozzle, the ambient pressure it exhausts to (unless the flow is choked), and the efficiency of the expansion. [5]

3. Rocket engine nozzle - Wikipedia

   en.wikipedia.org/wiki/Rocket_engine_nozzle

   The gas flow rate is constant (i.e., steady) during the period of the propellant burn. The gas flow is non-turbulent and axisymmetric from gas inlet to exhaust gas exit (i.e., along the nozzle's axis of symmetry). The flow is compressible as the fluid is a gas. As the combustion gas enters the rocket nozzle, it is traveling at subsonic velocities.

4. Gasoline pump - Wikipedia

   en.wikipedia.org/wiki/Gasoline_pump

   A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa ), [ 2 ] [ 3 ] petrol pumps (in Commonwealth countries), or gas pumps (in North America ).

5. Nozzle - Wikipedia

   en.wikipedia.org/wiki/Nozzle

   The hot gas is at a higher pressure than the outside air and escapes from the engine through a propelling nozzle, which increases the speed of the gas. [ 2 ] Exhaust speed needs to be faster than the aircraft speed in order to produce thrust but an excessive speed difference wastes fuel (poor propulsive efficiency).

6. Fast fuel system - Wikipedia

   en.wikipedia.org/wiki/Fast_fuel_system

   This includes mining, heavy construction, busses and railroad. Most larger earthmoving and mining vehicles with diesel fuel tanks over 150 US gallons (570 L) are equipped with a refueling Fast Fill System. These refueling Fast Fill Systems utilize an automatic shut off fuel nozzle, receiver and level control device.

7. Spray (liquid drop) - Wikipedia

   en.wikipedia.org/wiki/Spray_(liquid_drop)

   Examples include fuel injectors for gasoline and diesel engines, atomizers for jet engines (gas turbines), [12] atomizers for injecting heavy fuel oil into combustion air in steam boiler injectors, and rocket engine injectors. Drop size is critical because the large surface area of a finely atomized spray enhances fuel evaporation rate.
