A Venturi meter is a flow measurement device, commonly utilized in the water supply industry. A Venturi meter specifically uses a converging section of pipe to increase flow velocity. A corresponding reduction in pressure permits a determination of the flow rate.
The Venturi meter is based on the Venturi effect. The Venturi effect signifies a decrease in pressure caused by an increase in velocity that results from the narrowing of a tube through which a liquid flows. The Venturi effect only applies to the flow of liquids. The Venturi effect is named after an Italian physicist named Giovanni Battista Venturi who lived from 1746 until 1822.Learn More
According to About.com Scuba Diving, the Venturi effect states that when air is forced through a narrow tube, the air particles leave the tube traveling at a greater speed than when they entered the tube. This results in the formation of a vacuum at the end of the tube because the fast-moving air particles tend to drag some slower-moving air particles along with them.Full Answer >
Sir Isaac Newton did not invent the newton meter. Although the identity of the inventor remains unknown, it is unlikely that Newton invented it because the newton was defined and named in the 19th century, 60 years after his death in 1727.Full Answer >
A meter is approximately 39.37 inches long, the equivalent of 3.28 feet or 1.09 yards. It is also equal to 10 decimeters, 100 centimeters and 1,000 millimeters.Full Answer >
The Venturi effect is the creation of a partial vacuum when the flow of a fluid is restricted, increasing its speed of flow. Thus, a pipe with a fluid flowing through it which narrows at one point before widening again draws fluid from a second fluid-filled pipe attached to the narrow portion. This occurs because, as the fluid's kinetic energy increases, its pressure must decrease.Full Answer >
