Pressure drop is a term used to describe the change in pressure across a system. For example, in a typical garden hose the pressure in the hose is 40 psi and at sea level the atmospheric pressure is about 15 psi. Therefore, the pressure drop across the nozzle is 25 psi.

"Pressure Drop" is also the name of a song by Toots & the Maytals and an early album by Robert Palmer (featuring his cover version of the song). Later this song was redone by The Clash, and can be found on their compilation album Super Black Market Clash

"Pressure Drop" is also the name of a computer peripheral company designing and building products such as USB hubs and iPod docks.
