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. |
