- Hi,

Studying Bernoulli's equation derivation and am not understanding WHY is the second Force for the larger distance applied in the direction OPPOSITE to the flow of the velocity?

I am using this textbook figure:

https://openstax.org/books/university-physics-volume-1/pages/14-6-bernoullis-equation

The derivation starts at "We also assume that there are no viscous forces in the fluid, so the energy of any part of the fluid will be conserved. "

I figure that either the Force F2 is applied in the opposite direction because of some kind of resistance, but I'm not sure.

Thanks!

Thanks!
