So I recently looked into the venturi effect, only to be confused. I had always been aware that a lower available volume would result in a higher pressure, yet I had read that fluid passing through a constriction is actually subjected to less pressure than the diverging sides of a pipe. I had thought that the increase in fluid velocity was due to an increase in pressure (from a smaller volume).
Why is there less fluid pressure in a constriction as opposed to a section of a tube with a larger volume?
Is the decrease in pressure from the constriction the reason why fluid flows faster through it? I thought fluid went faster because it had to maintain the same volume/time ratio through a smaller volume, which should result in a higher pressure (force/volume=pressure).
I'd appreciate a clear answer.
