Moderate pressure can be measured with sufficient accuracy by using simple pressure gauges like U-tube manometers. But when very low or high pressures are to be measured with high accuracy, advanced and more complex gauges are required. Common advanced pressure gauges are listed with some details.
Hydraulics in Civil Engineering
Hydraulics is an important field in Civil Engineering that has to do with the mechanical properties of liquids. Whether the project is a tunnel, road or series of pipes running through a building, it’s important to know how the water will travel and what conditions the building will be safe under. Read more about topics like fluid mechanics, fluid machinery, irrigation, coastal waters and more.
Now we know pressure varies in a fluid. But that is not the sufficient information for hydraulics analysis. We need to know what the exact pressure at any particular point is in the fluid system. Hence, the need for pressure measurement methods and devices arises.
Fluids at rest have pressure as the major physical quantity to be considered, no flow behavior nor any shear forces. The fluid pressure results in the force acting on the bodies in contact with the fluid. In this article we will study how pressure develops and varies in a static fluid body.
The Hoover Dam was constructed over the Colorado River near Las Vegas. This article will explain the history and interesting features of the Hoover Dam.
Before starting the study of fluid behavior, its dynamics and statics, we should have a brief overview of the basic properties of fluids and also a basic knowledge of the terms and quantities defined for fluids. In this article we will take up these basic introductory aspects of the fluids.
