I'm sorry, but that statement is baffling. Is it possible to provide a link to more information?
As I previously said, tube length is not a factor in determining the Reynolds number. Also, I learned that as the Reynolds number (and turbulence) increases flow rate decreases. So if have a cite to your information Iâ€™d appreciate it.
"This observation is in agreement with the fact that the losses in a turbulent flow are much higher than in a laminar flow, and therefore the pressure drop per unit length will be greater, which is reflected in a larger frictional stress at the wall.
