Which of the following statement is an incorrect observation from the Moody’s diagram?

For a given relative roughness, the friction factor increases with increasing Reynolds number until the zone of complete turbulence is reached.

As the relative roughness increases, the value of the Reynolds number at which the zone of complete turbulence begins also increases.

Within the zone of complete turbulence, the Reynolds number has no effect on the friction factor.

For a given Reynolds number of flow, as the relative roughness is increased, the friction factor decreases.
