Pressure drop (often abbreviated as "dP" or "ΔP") [1] is defined as the difference in total pressure between two points of a fluid carrying network. A pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through a conduit (such as a channel, pipe, or tube).
In non ideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section.
"Pressure Drop" is a song recorded in 1969 by the Maytals for record producer Leslie Kong. The song appears on their 1970 album Monkey Man (released in Jamaica by Beverley's Records ) and From the Roots (released in the UK by Trojan Records ).
Pressure Drop is the second solo album by English singer 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 and the Maytals .
Pressure has dimensions of energy per unit volume, therefore the pressure drop between two points must be proportional to the dynamic pressure q. We also know that pressure must be proportional to the length of the pipe between the two points L as the pressure drop per unit length is a constant.
Pressure Drop hosted a weekly radio program on German's Sputnik under their alias Blood Brothers. [16] Titled Blood Brothers Broadcasting Corporation, it featured their own live DJ mixes, as well as guest mixes and interviews with musicians and producers, [17] and was available throughout Europe via the Astra satellite network.

The Kozeny–Carman equation (or Carman–Kozeny equation or Kozeny equation) is a relation used in the field of fluid dynamics to calculate the pressure drop of a fluid flowing through a packed bed of solids. It is named after Josef Kozeny and Philip C. Carman.
The Hazen–Williams equation is an empirical relationship that relates the flow of water in a pipe with the physical properties of the pipe and the pressure drop caused by friction. It is used in the design of water pipe systems [ 1 ] such as fire sprinkler systems , [ 2 ] water supply networks , and irrigation systems.
