Pressure

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.

Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa), for example, is one newton per square metre; similarly, the pound-force per square inch (psi) is the traditional unit of pressure in the imperial and US customary systems. Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure and the torr is defined as ¹⁄₇₆₀ of this. Manometric units such as the centimetre of water, millimetre of mercury and inch of mercury are used to express pressures in terms of the height of column of a particular fluid in a manometer.

Definition

Pressure is the amount of force acting per unit area. The symbol for pressure is p or P. The IUPAC recommendation for pressure is a lower-case p. However, upper-case P is widely used. The usage of P vs p depends on the field in which one is working, on the nearby presence of other symbols for quantities such as power and momentum, and on writing style.

Pressure (Sunscreem song)

"Pressure" is a 1991 dance single recorded by the British techno group Sunscreem, and written and produced by band members Paul Carnell and lead singer Lucia Holm from the act's 1993 set *O₃. "Pressure" was the group's first single release in the United Kingdom, where it peaked at number 60 on the country's pop chart, but it became a major club hit in the United States in wake of the success of "Love U More", where it was released as "Pressure US" with a new remixed version and went to number one on the dance chart for one week in June 1993, their second of three number ones. The re-released version reentered the UK charts afterwards, peaking at number 19 in 1993.

I Need You (album)

I Need You is the third compilation album from American recording artist LeAnn Rimes. The album was first released on January 30, 2001, through Curb Records to help satisfy Rimes' recording contract obligations during litigation with the label and her management. Rimes publicly disowned the album just days after its release, causing it to be discontinued. The album was then officially released by Rimes on March 26, 2002, with four additional tracks and a new recording: "Light the Fire Within". In 2008, the album was released as a package with Rimes' debut album, Blue (1996).

I Need You received mixed reviews by music critics, who praised its pop appeal but criticized the selection of the songs, noting that none of them made a significant impact on the listeners. In the United States, the album peaked at number one on the Billboard Top Country Albums chart, and reached number ten on the Billboard 200. Internationally, it peaked at number four on the Finnish Albums Chart, number ten on the Canadian Albums Chart, and number eleven on both the Austrian Albums Chart and the Irish Album Chart. The album was certified Gold by the Recording Industry Association of America (RIAA), among other organizations, and was certified platinum by both Music Canada and the IFPI Finland.
