Does Slower Flowing Fluid Experience Less Pressure Drop?

Click For Summary
SUMMARY

The discussion centers on the relationship between fluid velocity and pressure drop in vertical pipes. It is established that in laminar flow, the pressure drop is quadratically proportional to the mean velocity of the fluid. Therefore, slower flowing fluids experience less pressure drop compared to faster flowing fluids. This principle is crucial for understanding fluid dynamics in various applications.

PREREQUISITES
  • Understanding of fluid dynamics principles

Lets say water was rising vertically up a pipe at a lower pressure and lower velocity. Is the pressure drop the same in faster and slower moving fluids or does slower moving fluid lose less pressure from pressure drop.

The pressure drop in laminar regime is quadratically proportional to the mean velocity of the fluid.
 
I don't understand your wording of the sentence. But to reword my question is to say will a slow flowing fluid rising vertically not see much of a loss in pressure due to gravity.
