When fluid flows through a pipe there will be a pressure drop that occurs as a result of resistance to flow. There may also be a pressure gain/loss due a change in elevation between the start and end of the pipe. This overall pressure difference across the pipe is related to a number of factors Friction between the fluid and the wall of the pipe.

Hydraulic Pressure Loss. Hydraulic pressure loss is everywhere . As a fluid is forced from one point to another, certain forces act on the fluid that cause it to lose and in one case (the case of elevation) potentially gain pressure.
