WebThe flow nozzle is generally used for measuring the flow of steam as well as non-viscous, erosive and high-velocity media. It can be used in a wide variety of applications that include steam, air, water, vapour, gas, chemical substances and high temperatures. For applications with erosive media a hardened internal surface is available. The ... WebIn effect, the flow nozzle is a venturi meter that has been simplified and shortened by eliminating the gradual downstream expansion (figure 14-3). The streamlined entrance of the nozzle causes a straight jet without contraction, so its effective discharge coefficient is nearly the same as the venturi meter. Flow nozzles allow the jet to expand ... show offline steam

Therefore, venturimeters should be installed following the manufacturer’s guidelines. Generally, the following guidelines should be followed when installing venturi meters: The direction of flow in the venturi meter should be checked and set up to agree the flow direction.

WebThe Venturi effect describes how the rate of fluid flow in an enclosed system changes as the flow enters a constricted channel. This change in fluid flow rate through a channel can be described using Bernoulli’s principle. The Venturi effect and Bernoulli’s equation makes statements about conservation of energy, conservation of momentum ... WebSep 22, 2009 · INTRODUCTION. This meter uses a fascinating effect that occurs when gas flows at very high velocity through a nozzle. As the gas is sucked through the nozzle, the velocity increases as the cross-section of the nozzle passage decreases toward the throat. At the throat, the maximum achievable velocity is sonic – the speed of sound.

WebA venturi meter is a way to measure flow in a pipe. The venturi is a section of pipe where the diameter is gradually reduced to some smaller area then gradually increased to the initial diameter To measure the flow in the pipe you measure the pressure at the inlet and then again at the narrowest section of the venturi. Assuming no friction.
