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.

Powerhouse (TV series)

PowerHouse is a United States television series produced by the Educational Film Center at Northern Virginia ETV and aired on PBS for 16 episodes in 1982 (two episodes never aired). It billed itself as "a 16-part series for young people and their families," with the target audience being primarily kids, preteens, teenagers,& young adults, and it was widely praised by educational groups. The series was later rerun by Nickelodeon in the mid-1980s.

Description

Set in Washington, DC, PowerHouse is focused on the adventures of a racially and ethnically diverse group of five teenagers and one adult from the inner city, based at a former boxing and sports gym headquarters turned community center for kids and teens. The center was founded by Brenda Gaines, a woman who inherited the place from her late father, a former boxing champion. The basic theme of the series is that every person is a source of creativity and power. “We all have a PowerHouse deep down inside,” it said in the theme song of the show.

Powerhouse (shop)

Powerhouse was a United Kingdom electrical goods retail chain which went into administration in 2003 and finally entered receivership in August 2006. At one time it was the third largest trader in the UK electrical goods market.

Company history and details

Powerhouse was born in 1992 from a management buyout of the retail arms of Southern Electric, Midlands Electricity and Eastern Electricity. The head office was based in Bicester. In an attempt to differentiate themselves in the market they positioned themselves as 'local experts' with each stores main sign bearing the towns name. To fill gaps in their product lineup many stores had concessions for Time Computers and their short-lived mobile phone arm Time Talk. There was also a close relationship with Sony - all stores up until the PRG buyout had 'Sony In-Store' sections where Sony products were isolated on backlit gondolas. nPower were also partners, with Powerhouse acting on their behalf to sign up new customers. This was a sound theory, as Powerhouse's strengths were in the MDA sectors and these deals helped their offering look competitive. However, Time Computers was not in good shape. Time Talk barely lasted 12 months. All Time concessions had closed by 2002 but were not officially refurbished. It was left to the individual store to best use the space as they saw fit.
