Many oxygen therapy devices employ the Venturi effect to accomplish air entrainment for the purpose of diluting 100% oxygen (used as the source gas) with room air.
Figure 2 is a view of building showing how the Venturi effect can cause excessive wind loading to other structures.
The present case reinforces the notion that SAM is mostly due to the drag flow phenomenon and not to the Venturi effect According to Sherrid et al.
This clever and practical device attaches to your garden hose and the water pressure creates a venturi effect which sucks up any dirt and debris.
THIS CLEVER BRITISH INVENTION ATTACHES TO YOUR GARDEN HOSE AND THE WATER PRESSURE CREATES A VENTURI EFFECT WHICH SUCKS UP ANY DIRT AND DEBRIS.
whereby hot air will escape via grilles at the peak of each aperture; such air flows will be further enhanced by the Venturi effect of winds over the roof.
(14) Passing a high-pressure [O.sub.2] jet through a narrow orifice creates a Venturi effect and results in air entrapment and a marked increase in the total flow.
As the pressure reduces, the flow rate increases, creating a Venturi effect, puffing the cone back into the doughnut.
The sudden air acceleration creates a local under-pressure due to the Venturi effect. The relative pressure stays negative as the air travels inside the air ring-film gap.
jeanneli builds chimneys up to 23 ft (7 m) tall that use the Venturi effect to suck air into the nest, thus cooling it by the evaporation of water.
Finally, the airflow caused by the rotation of the disc, combined with the "scoop" design of AVOS products, creates a "Venturi effect," which directs the air flow away from the grinding zone.
