Theoretical flow rate

Webb2 okt. 2015 · 1 Answer Sorted by: 1 The transition from Hagen-Poiseuille to Darcy-Weisbach behaviour happens when the flow regime switches from laminar to turbulent. Note that the DW equation has a fudge factor that describes the energy loss due to turbulence. This friction factor varies with flow rate. WebbSee Full PDFDownload.
