n: a venturi tube used to measure fluid flow when a low permanent pressure drop is required for measurement

n: A mud-flow device, also called a mud hopper, in which materials are put into the circulating mud system. The mud hopper is powered by a centrifugal pump that flows the mud at high velocity through a venturi nozzle (jet) below the conical-shaped hopper. Dr

n: a device employing a venturi nozzle through which a highpressure stream creates a lower pressure or a vacuum into which the gas to be compressed flows. The gas is discharged from the nozzle with the expanded highpressure medium.

n: a device to hold or feed drilling-mud additives. See mud-mixing devices. jet mixer n: a cement mixing system that combines dry cement with a jet of water. The turbulence from the water thoroughly mixes the cement slurry.

a shaped nozzle.

n: the drop in pressure resulting from the increased velocity of a fluid as it flows through a constricted section of a pipe.

n: a nozzle that, because of the venturi effect, increases the velocity of a fluid flowing through it.

n: a short tube with a calibrated constriction that is used in instruments or devices such as jet hoppers. It was developed to take advantage of the principle that a fluid flowing through a constriction has increased velocity and reduced pressure.

n: a flow meter used to determine the rate of flow and employing a venturi tube as the primary element for creating differential pressures in flowing gases or liquids. Compare orifice meter.
