the venturi tube

The Venturi tube is a special element designed to measure the flow of liquid through a pipeline. The gadget works by building up a pressure difference as liquid passes through a narrower section of the tube. As the liquid flows through this constriction, it speeds up and its pressure drops. To the point that this is an important concept for us to understand how does the Venturi tube works.

Measuring Fluid Flow with the Venturi Tube

First, we mount the Venturi tube in a pipe, where there is the flowing liquid. When the fluid comes into the tube, it reaches a narrow section, and at this stage, it starts moving faster and faster. The increased velocity results in a pressure differential across the narrow section of the tube. In other words, we can easily use pressure gauges to measure these pressure differentials and hence the pressure changes. This means that we can find out how quickly the liquid is moving through the pipe. Such a process is very useful in many applications as well where flow rate of liquid is desired.
