Calculation of pressure loss in a straight pipe for laminar flow regime of an incompressible and single-phase fluid flow only.
Generally this function is numerically best used for the compressible case , where the pressure loss (dp) is known (out of pressures as state variable) in the used model and the corresponding mass flow rate (M_FLOW) has to be calculated. On the other hand the function dp_laminar_DP is numerically best used for the incompressible case if the mass flow rate (m_flow) is known (as state variable) and the pressure loss (DP) has to be calculated. See more information.
Type: MassFlowRate (kg/s)
Description: Output for function dp_laminar_MFLOW
