Rigid Line No States  Losses of a rigid line as a function of Reynolds number

The RigidLineNoStates component describes the laminar/turbulent flow through a circular, smooth rigid line (that is, it calculates the flow rate q as a function of pressure drop dp). There are two flow modes:

0 < Re < ReCrit

laminar (Hagen-Poiseuille)

ReCrit < Re

turbulent (Blasius)

The functions q = q(Re) and q = q(dp) are unique.
