functiondp_internalFlowOverall_DP
Pressure loss of internal flow | calculate pressure loss | overall flow regime | surface roughness | several geometries
Extends from Modelica.Icons.Function (Icon for functions).
Information
Calculation of pressure loss for an internal flow through different geometries at overall flow regime for incompressible and single-phase fluid flow considering surface roughness.
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_internalFlowOverall_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.
