A hydraulic line is normally treated as an ideal connection, with no pressure drop being included in the simulation.
A frictional loss can be entered via the
Physical model options. If you select
Simple resistance, only the
Hydraulic resistance parameter will be included in the simulation.
If you select
Pipe model (Hagen-Poiseuille/Blasius), a complex empirical calculation is carried out using a model based on Hagen-Poiseuille for laminar flows and a model based on Blasius for turbulent flows, utilizing the Reynolds number and the wall surface roughness.
