Filtration equivalence

Pressure loss in uid hoses

Pressure drop is the resistance that prevents material from moving forward in the pipe. Two pipe

variables influence this resistance : the (inside/internal) diameter and the pipe length. The pump

will generate a pressure, strong enough to move the fluid material through the pipe (or hose) to the

material pipe outlet. This pressure must be enough to overcome the original pressure drop.

While it is hard to reduce the pipe length, it is relatively easy to select an appropriate internal pipe

diameter.
