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.
 
Physics news on Phys.org
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.
