It then needs two hours to settle as it is pumped at high pressure.
Fracking is a technique involving pumping water and chemicals into shale rock at high pressure to extract gas.

Liquid-fuelled rocket engines work by mixing the fuel (in this case kerosene) with liquid oxygen at high pressure.
Fracking is a technique where water and chemicals are pumped into shale rock at high pressure to extract gas.

Fracking is a controversial process that involves pumping water and chemicals into shale rock at high pressure to extract gas.
Fracking is a drilling process that frees gas from deep rock deposits by injecting wells with chemical-laced water at high pressure.
The Stirling cycle describes a phenomenon where a confined volume of gas expands at high pressure and contracts at low pressure.
Fracking is the process of blasting water at high pressure into shale rock to release oil or gas held within it.
Fracking is a technique of shale gas extraction that involves pumping water and chemicals into shale rock at high pressure to extract gas.
It extracts oil from the ground using a method called fracking - pumping down a mixture of sand, water and chemicals at high pressure.
About 25, 000 wells a year are being fracked, a process in which water, chemicals and sand are injected at high pressure underground to release trapped natural gas.
Under the process of fracking, oil or gas is extracted from shale rock by pumping a mixture of sand, water and chemicals into the rock at high pressure.
This year he completed what is believed to be the first ever fracture stimulation procedure in Turkey: injecting a mixture of water and sand at high pressure down the wells to break up rock and release gas.
The bans stem from local residents' concerns about potential adverse impacts if the state lifts its 5-year-old moratorium on gas drilling using high-volume hydraulic fracturing, or fracking, which frees gas from deep shale deposits by injecting wells with chemical-laced water at high pressure.
Hydraulic fracturing pumps many thousands of gallons of mainly water and sand, with a few chemicals, at high pressure into tight gas-bearing shale deposits (hardened muds), creating cracks that allow gas to flow back up the well to the surface ( Shale Shock).
Out of that it can then give you a small flow of water at a high pressure.
The assertion is that hydraulic fracturing fluids, which are injected at high speed and high pressure to create cracks in the shale rock that traps natural gas, will seep into underground water aquifers.
FORBES: The Sierra Club Fails An Environmental Consistency Test
Even a relatively small amount of gas a can cause big problems because a gas bubble will expand massively as it moves from high pressure at the seafloor to lower pressure at the surface.
At a high temperature and pressure, gasification converts coal, or other carbon fuels, into synthesis gas that is either burned in a turbine to produce electricity, as in Summit's case, or turned into other products, like diesel oil, fertilizer and pipeline-quality natural gas.
Ashleigh Griffin ( 2008 FWIS Fellow), Elizabeth Murchison ( 2009 FWIS Fellow), Araxi Urrutia ( 2007 FWIS Fellow) and Patricia Alireza ( 2009 FWIS Fellow) provided fascinating insights into their work on the behaviour of bacteria living in the lungs of cystic fibrosis patients, transmissible cancers in Tasmanian Devils, human gene and genome evolution and the effects of high pressure at quantum level.
To prevent this, milk is forced under extreme pressure and at high velocity to pass through tiny passages by a piston pump.
The fellowship will help Dr Alireza purchase essential equipment to start a new high pressure laboratory at UCL and to continue the collaborations she has established with other institutions both in the UK and around the world.

We believe that the margins are already at very high levels and there will be pressure from pay-TV service providers to stall the growth in the carriage fee for cable channels.
FORBES: Disney's Multi-Platform Distribution Deals Can Lift Margins And Outlook
If I roll them evenly, this disproportionate edge pressure remains, and at a high speed the skis bend into two differently shaped arcs, rather than ideally parallel twins, meaning they are making two different turns of different radii and different speeds, and occasionally this results in a seemingly unexplainable fall.
Fracking involves drilling a borehole before a high-pressure water mixture is directed at the rock to release the gas.
Beware of high-pressure tactics that are aimed at forcing you to commit yourself before you understand the nature of the deal.
And then I would just point you to what I said before about these are high-pressure jobs with a lot at stake.
Patients with high BMIs or with chest pain or pressure at presentation were less likely to have a false-positive activation.

Leeds' struggles on the pitch have led to frustration among an expectant fanbase who are never shy in voicing their frustration, increasing the burden on the players at a time of the season when pressure is already high.
