Hydraulic mining. Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. [1] In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal .

The oil and gas industry is usually divided into three major sectors: upstream (or exploration and production - E&P), midstream and downstream. The upstream sector includes searching for potential underground or underwater crude oil and natural gas fields, drilling exploratory wells, and subsequently operating the wells that recover and bring the crude oil or raw natural gas to the surface.
Deformed coral limestone showing flattening accommodated both by plastic deformation of the corals and pressure solution along stylolites. In structural geology and diagenesis, pressure solution or pressure dissolution is a deformation mechanism that involves the dissolution of minerals at grain-to-grain contacts into an aqueous pore fluid in ...
Private property in the means of production is the central element of capitalism criticized by socialists. In Marxist literature, private property refers to a social relationship in which the property owner takes possession of anything that another person or group produces with that property and capitalism depends on private property.
Pressure in a vortex A plughole vortex. The fluid motion in a vortex creates a dynamic pressure (in addition to any hydrostatic pressure) that is lowest in the core region, closest to the axis, and increases as one moves away from it, in accordance with Bernoulli's principle. One can say that it is the gradient of this pressure that forces the ...
APEX is used for developing and deploying cloud, mobile and desktop applications. The platform is a web-based integrated development environment (IDE) with a range of features including wizards, drag-and-drop layout and property editors to simplify the process of building applications and pages.

Overpressure ammunition. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus ), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics ), but less than the pressures generated by a proof round.
