  5. Qmass = ρ · Q. Where: Q = volumetric flow rate (m3/s, in3/s) Qmass = Mass flowrate (kg/s, lbs/s) A1 = area = Π · r2 (mm2, in2) A2 = area = Π · r2 (mm2, in2) r1 = radius inlet at A1 (mm, in) r2 = radius inlet at A2 (mm, in)

What is beta ratio in Venturi?

BETA RATIO (β): The ratio of the inside of the diameter throat of the venturi to the inside diameter of the pipe at the plane of the upstream Pressure Taps.

How much water does a venturi pump use?

The venturi effect occurs when liquid flows through a compressed section of pipe. The result is increased fluid velocity & reduced fluid pressure. By using the pressure from the garden hose, this simple but effective submersible pump will drain up to 4,500 litres of water per hour with optimal water pressure.

Does a Venturi increase pressure?

A Venturi is a system for speeding the flow of the fluid, by constricting it in a cone shape tube. In the restriction the fluid must increase its velocity reducing its pressure and producing a partial vacuum. As the fluid leave the constriction, its pressure increase back to the ambient or pipe level.

What is the acceptable beta ratio range?

0.1 to 0.75
Standard orifice plates are sized to a beta ratios from 0.1 to 0.75 (beta ratio = d/D, where “d” is the bore size and “D” is the internal diameter of the pipe/meter tube).

What is beta ratio?

Beta Ratio equals the ratio of the number of particles of a minimum given size upstream of the filter to the number of particles of the same size and larger found downstream. Simply put, the higher the Beta Ratio the higher the Capture Efficiency of the filter.

How much vacuum can a venturi pull?

27 in.-Hg
Venturi-type vacuum generator produces vacuum from stream of compressed air. Most recent designs pull vacuum to 27 in. -Hg from a source of compressed air of less than 50 psig.

How do you use a venturi pump?

The Venturi system increases the sucking capacity of any air compressor. To configure a Venturi Vacuum, plug the compressor into one end, move the switch to the vacuum setting, and plug the other end into a vacuum device.

How do you calculate ideal flow rate?

If you can see the fluid flowing, you can measure its velocity, and that means all you need is the area through which the fluid is flowing to calculate the flow rate using the formula ​Q​ = ​A​ × ​v​.
