A pump is a device used to move fluids (liquids or gases) or sometimes slurries by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.
Pumps must have a mechanism which operates them, and consume energy to perform mechanical work by moving the fluid. The activating mechanism is often reciprocating or rotary. Pumps may be operated in many ways, including manual operation, electricity, a combustion engine of some type, and wind action.
A positive displacement pump causes a fluid to move by trapping a fixed amount of it and then forcing (displacing) that trapped volume into the discharge pipe.
Some positive displacement pumps work using an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. The volume is constant given each cycle of operation.
Amy Jade Winehouse (14 September 1983 – 23 July 2011) was an English singer and songwriter known for her powerful deep contralto vocals and her eclectic mix of musical genres including R&B, soul and jazz. Winehouse's 2003 debut album, Frank, was critically successful in the UK and was nominated for the Mercury Prize. Her 2006 follow-up album, Back to Black, led to six Grammy Award nominations and five wins, tying the then record for the most wins by a female artist in a single night, and made Winehouse the first British female to win five Grammys, including three of the "Big Four": Best New Artist, Record of the Year and Song of the Year.
In 2007 she won a Brit Award for Best British Female Artist; she had also been nominated for Best British Album. She won the Ivor Novello Award three times: once in 2004 for Best Contemporary Song (musically and lyrically) for "Stronger Than Me", once in 2007 for Best Contemporary Song for "Rehab", and once in 2008 for Best Song Musically and Lyrically for "Love Is a Losing Game".
Katheryn Elizabeth Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter and actress. Perry grew up with gospel music, and during her first year of high school she pursued a music career as Katy Hudson, releasing her first studio album called Katy Hudson which failed to chart. She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.
She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".
