When the valve is opened, gas flows through orifices into venturi tubes, where it is mixed with air.
Differential pressure is measured between two segments of a venturi tube that have a different aperture.
The pressure difference between the two segments is directly proportional to the flow rate through the venturi tube.
The effects explained by Bernoulli's Principle can be produced by sending a fluid through a venturi tube, or venturi, a short tube whose diameter tapers to a relatively narrow section at its middle.
The venturi tube is used in several kinds of devices, including instruments that measure flow of fluids.
Gas is mixed with air in venturi tubes or simply 'venturis'.
He could see docking gear, comms antennae, thrusters' venturi tubes, airlock panels and windows.
Dragsters use a scavenger system and venturi tube in the exhaust to draw out combustion gases and maintain a small amount of vacuum in the crankcase to prevent oil leaks on to the race track.
Follow the cleaning and storage procedures in the owner's manual, paying special attention to the burners, venturi tubes and igniter.
