Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Calculation of the mean convective heat transfer coefficient kc for a helical pipe in the laminar flow regime. Note that additionally a failure status is observed in this function to check if the intended boundary conditions are fulfilled. See more information .
