functionReynoldsNumber_m_flow

Return Reynolds number from m_flow, mu, D, A

Extends from Modelica.Icons.Function (Icon for functions).

Information

Simplified calculation of Reynolds Number for flow through pipes or orifices; using the mass flow rate m_flow instead of the velocity v to express inertial forces.
  Re = |m_flow|*diameter/A/μ
with
  m_flow = v*ρ*A
See also Pipes.BaseClasses.CharacteristicNumbers.ReynoldsNumber.
