WOLFRAM SYSTEM MODELER
ReynoldsNumber_m_flowReturn Reynolds number from m_flow, mu, D, A |
SystemModel["Modelica.Fluid.Pipes.BaseClasses.CharacteristicNumbers.ReynoldsNumber_m_flow"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Simplified calculation of Reynolds Number for flow through pipes or orifices; using the mass flow ratem_flow
instead of the velocity v
to express inertial forces.
See also Pipes.BaseClasses.CharacteristicNumbers.ReynoldsNumber.Re = |m_flow|*diameter/A/μ with m_flow = v*ρ*A
