Drag equation by experiment. Of particular importance is the formula_8 dependence on flow velocity, meaning that fluid drag increases with the square of flow velocity. When flow velocity is doubled, for example, not only does the fluid strike with twice the flow velocity, but twice the mass of fluid strikes per second. Therefore, the change of momentum per second is multiplied by four. Force is equivalent to the change of momentum divided by time. This is in contrast with solid-on-solid friction, which generally has very little flow velocity dependence. The drag force can also be specified as, formula_9 where, "P" is pressure
Our Velocity game Our Velocity "Our Velocity" is the first single from "Our Earthly Pleasures", the second album from the band, Maxïmo Park. The single was released two weeks prior to the release of the album, on 19 March 2007. The music was written by Duncan Lloyd and the lyrics by Paul Smith of the band. The video of the song features the band being multiplied in a white room while playing the song. It was directed by Nima Nourizadeh. The song has been highly regarded and in VH1's "50 Greatest Songs of 2007 So Far" it placed at number 1. The
