Pressure drop

Pressure drop is defined as the difference in pressure between two points of a fluid carrying network. Pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through the tube. The main determinants of resistance to fluid flow are fluid velocity through the pipe and fluid viscosity. Pressure drop increases proportional to the frictional shear forces within the piping network. A piping network containing a high relative roughness rating as well as many pipe fittings and joints, tube convergence, divergence, turns, surface roughness and other physical properties will affect the pressure drop. High flow velocities and / or high fluid viscosities result in a larger pressure drop across a section of pipe or a valve or elbow. Low velocity will result in lower or no pressure drop.

Pressure Drop (album)

Pressure Drop is the second solo album by Robert Palmer, released in 1975. Palmer is backed by Little Feat and other musicians. The title track is a cover version of the reggae hit by Toots & the Maytals. However, many other songs on the album use "New Orleans funk ... along with smooth, dated disco ballads smothered in strings". Continuing his association with Little Feat started by his cover of "Sailing Shoes" on his 1974 debut album Sneaking Sally Through the Alley, Feat was used as backing band on several cuts, most notably Lowell George's slide guitar on "Here With You Tonight". George also contributed the tune "Trouble" on which Feat pianist Bill Payne plays the intro. David Jeffries' review says that the album is considered "too blue-eyed and polished for fans of Palmer's more gutsy moments" but concludes that "Pressure Drop has grown into the great overlooked album in Palmer's discography".

The album peaked at No. 136 in the US.
