Hydraulic fracturing is a process in which fractures in rocks below the earth’s surface are opened and widened by injecting chemicals and liquids at high pressure: used especially to extract natural gas or oil. How the process works: The process includes steps to protect water supplies. To ensure that neither the fluid that will eventually be pumped through the well‚ nor the oil or gas that will eventually be collected‚ enters the water supply‚ steel surface or intermediate casings are inserted

Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster’s Medical Dictionary‚ via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics‚ including da Vinci‚ Mariotte and Boyle. The scientist who discovered the

CHAPTER 5 HYDRAULIC STRUCTURES 1 LEARNING OBJECTIVE(S): Know about the basic features of hydraulic structures; Identify the different types and use of hydraulic structures; Determine the flow by using different types of hydraulic structures. 2 Introduction A hydraulic structure is a structure submerged or partially submerged in any body of water. Hydraulic structures are artificial or natural objects that can be used to divert‚ disrupt‚ restrict‚ stop or manage the natural

Laboratory Report for Sluice Gate and Hydraulic Jump Introduction. In this lab exercise we were supposed to analyse the Hydraulic jump through the Sluice gate‚ and to discuss about the energy displacement through that process. Hydraulic jump is known as the change flow which changes from the supercritical flow to the sub-critical flow‚ this change occurs due to the loss turbulence in an open tunnel. In basic terms this happens when there is a sudden rise in the water levels‚ due to the

Hydraulic Jump Experiment SUMMARY The Objective of this experiment is to observe the flow patterns and behaviour of the water before after the jump Also to quantify the energy lost due to a hydraulic jump. The observed and theoretical ratios of upstream and downstream depths will be compared‚ this will show the limitations to purely theoretical analysis. The experiment showed that a hydraulic jump occurs when when liquid at high velocity discharges into a zone of lower velocity

MEASURING AND MODELLING HYDRAULIC FLUID DYNAMICS AT HIGH PRESSURE - ACCURATE AND SIMPLE APPROACH. International Journal Of Fluid Power‚ 13(2)‚ 51-59. ASTRACT: Dynamic properties of hydraulic fluids have to be taken into account in ever increasing fluid power applications. The main reasons are increasing accuracy demands in control and modeling‚ as well as increasing operating pressure and temperature ranges. Moreover‚ the already wide spectrum of different hydraulic fluids is also expanding all

HYDRAULICS IN MISSILES Nowadays‚ the electro-hydraulic actuator plays an important role in some modern tactical missiles. High power‚ great robustness and high tracking precision are the most significant demands for the missile actuator. Therefore an advanced method of active disturbance rejection control (ADRC) is presented aiming at the dynamics of the system are highly nonlinear and have large extent of model uncertainties‚ such as tremendous changes in load. Firstly‚ a novel ADRC controller
