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 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
