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/universityphysicsvolume1/pages/146bernoullisequation
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!
