WebMay 27, 2024 · Pressure drop is the difference in pressure between two points provided that there is a fluid flow between those points. So pressure drop occurs when a fluid (gas/liquid) material enters one point of the piping system and exits through the other points. In that case, process piping systems should have losses of pressure, and this … WebInformally, a flow may be viewed as a continuous motion of points over time.
