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 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.
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.
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.

To calculate the pressure drop in a given reactor, the following equation may be deduced: = + | |. This arrangement of the Ergun equation makes clear its close relationship to the simpler Kozeny-Carman equation, which describes laminar flow of fluids across packed beds via the first term on the right hand side.
In the integral form, the total pressure drop = is in units (), and is the length of the sample in units (), the Darcy's volumetric flow rate , or discharge, is also defined in units (/) and the cross-sectional area in units (). A number of these parameters are used in alternative definitions below.
