The more I learn about Bernoulli's the less I feel I understand it
The problem statement
If I had a ball (balloon) filled with fluid at pressure P being acted on by two opposing forces F+ and F-
F+ being larger than F- there would be a net force accelerating the ball to the right but the pressure P would remain the same.
Now if I was to examine the ball as a parcel of fluid in a continuum and have a higher pressure (HP+) ~ F+ acting on one side and a lower pressure (HP-)~ F- on the other side.
Then I would also see the whole ball of fluid being accelerated to the right but the pressure inside the ball would also decrease from HP on the left side to LP on the right side
My question.
What action caused by the unbalanced external forces , is causing the internal pressure of the ball to decrease ?
