Can you please answer why the force at area A2 is opposite to the direction of liquid flow. What is the cause of force F2?

It would be nice to learn about laminar (water) geometry. How water geometry changes with physics and chemistry.

This channel have helped me understand most of my physics lectures! Thanks! I want to ask one thing, do we can just simply cross out the V when the V for each is different in value?

You're welcome! Happy to hear that.. By the nature of the argument, we assume that the volume that moves is the same. So yes, we need to cross out the volume. But if for some reason you want to assume the volumes are not the same, no, you cannot cross them out.

is it is right because if you change the cross section area then there is change in velocity so it is not applicable for both cross section area

I haven't reached Fluid Dynamics yet, but this was definately helpful and gives me an idea where the subject is heading. Thanks for video. Physics is my hobby, so I take my time getting to that chapter.

Aamna Fayyaz it is the work done against the P1 ,and according to newton there is a reaction to every action equal and should be (opposite).............

m is NOT the mass of the entire fluid. It is the mass of the small piece of fluid of length dl1 at left end of pipe. You did not consider the energy of the bulk of the fluid between the small regions at each end of the pipe. This is an important point. Most annoyingly, this subtlety is omitted from numerous videos that I've seen on this derivation, causing me much confusion. The energy of this part of the fluid does not change assuming that in the case of KE, the velocity of any particle of the fluid at a fixed point in the tube does not change in time. That is why the change in energy of the entire amount of fluid only involves the mass elements at either end of the pipe.

what a mess, and nice reading. he failed to show the energy conservation but everything else. the net work done on the fluid = internal energy change of the fluid.
