Flow regime in pipe
WebAt lower values of R e (R e < 2, 000) flow is in the laminar flow regime, while at higher values of R e (R e > 4, 000) flow is in the turbulent flow regime. As we see in the Moody Diagram, Figure 6.06, in the turbulent … WebFlow Regimes. For low Reynolds numbers the behavior of a fluid depends mostly on its viscosity and the flow is steady, smooth, viscous, or laminar and n = 1. For high …
