Aspirator (pump) - Wikipedia

Aspirator (pump) - Wikipedia

An aspirator is a type of ejector-jet pump, which produces vacuum by means of the Venturi effect.. In an aspirator, fluid (liquid or gaseous) flows through a tube that first narrows and then expands in cross-sectional area. When the tube narrows, the fluid pressure decreases.

Venturi eductors or vacuum pumps

Venturi eductors or vacuum pumps

A Venturi vacuum pump is based on the principle of the Conservation of Energy which states that, in a steady flow, the sum of all forms of mechanical energy in a fluid along a line is the same at all points. That is, the sum of the kinetic energy (reflected in the form of velocity) and potential energy (pressure) must remain constant. .

Flowrate Calculation for a Venturi - eFunda

Flowrate Calculation for a Venturi - eFunda

Calculate the flowrate measured by a venturi-style flowmeter. Solving for the upstream velocity V a and multiplying by the cross-sectional area A a gives the volumetric flowrate Q, : Ideal, inviscid fluids would obey the above equation. The small amounts of energy converted into heat within viscous boundary layers tend to lower the actual velocity of real fluids somewhat.
