The discussion centers on the relationship between turbulence and the Reynolds number, specifically addressing the misconception that turbulence is dependent on the Reynolds number. It is established that in the fully turbulent flow regime, as indicated on the Moody diagram, the friction factor (f) remains constant regardless of changes in the Reynolds number. Instead, the friction factor is solely influenced by the relative pipe roughness in this region. This clarification is crucial for understanding fluid dynamics in engineering applications.
PREREQUISITESEngineers, fluid dynamics students, and professionals involved in hydraulic design or pipe flow analysis will benefit from this discussion.

First, it's discussing the friction factor f as it's plotted on the Moody diagram:
In the zone where the flow is completely turbulent, i.e. to the right of the dashed line, the friction factor is constant w.r.t. the Reynolds number. In this region, the friction factor f depends on the relative pipe roughness only.
Can you explain this phenomenon?SteamKing said:You're not correctly comprehending what this slide is saying.

this is the book that i use . can you expalin why during the complete turbulent , it is independent of reynold number ?SteamKing said:
