functiondp_turbulent_MFLOW
Pressure loss of straight pipe | calculate mass flow rate | turbulent flow regime | surface roughness
Extends from Modelica.Icons.Function (Icon for functions).
Information
Calculation of pressure loss in a straight pipe for turbulent flow regime of an incompressible and single-phase fluid flow only considering surface roughness.
Generally this function 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. On the other hand the function dp_turbulent_DP 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. See more information.
