Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Calculation of a generic pressure loss with linear or quadratic dependence on volume flow rate. The function can be used to calculate pressure loss at known mass flow rate or mass flow rate at known pressure loss.
Generally this function is numerically best used for the incompressible case , where the mass flow rate (m_flow) is known (as state variable) in the used model and the corresponding pressure loss (DP) has to be calculated. On the other hand the function dp_volumeFlowRate_MFLOW is numerically best used for the compressible case if the pressure loss (dp) is known (out of pressures as state variable) and the mass flow rate (M_FLOW) has to be calculated. See more information.
