  2. Vapor recovery - Wikipedia

    en.wikipedia.org/wiki/Vapor_recovery

    Gas nozzle with vapor recovery. Vapor (or vapour) recovery is the process of collecting the vapors of gasoline and other fuels, so that they do not escape into the atmosphere. This is often done (and sometimes required by law) at filling stations, to reduce noxious and potentially explosive fumes and pollution.

  3. Air lock - Wikipedia

    en.wikipedia.org/wiki/Air_lock

    The gas, being less dense than the liquid, rises to any high points. This phenomenon is known as vapor lock, or air lock. Flushing the system with high flow or pressures can help move the gas away from the highest point. Also, a tap (or automatic vent valve) can be installed to let the gas out.

  4. Choked flow - Wikipedia

    en.wikipedia.org/wiki/Choked_flow

    Orifice plate includes derivation of non-choked gas flow equation. de Laval nozzles are venturi tubes that produce supersonic gas velocities as the tube and the gas are first constricted and then the tube and gas are expanded beyond the choke plane. Rocket engine nozzles discusses how to calculate the exit velocity from nozzles used in rocket ...

    Typical plug-nozzle garden sprayer with a trigger-pull lever (at the back) to control the position of the plug and valve. Common garden hose trigger nozzles are a simple example of the plug nozzle and its method of operation. In this example the nozzle consists of a conical or bell shaped opening with a plug on a movable rod positioned in front ...

  9. Isentropic nozzle flow - Wikipedia

    en.wikipedia.org/wiki/Isentropic_Nozzle_Flow

    is the density of the gas (kg/m 3) is the temperature of the gas (K) is the cross sectional area of the nozzle at the point of interest (m 2) is the cross sectional area of the nozzle at the sonic point, or the point where gas velocity is Mach 1 (m 2). Ideally this will occur at the nozzle throat.
