I initially started to be interested in fluid pressure and pipes to learn electricity. It seemed the only way I could help my head to get around some electrical concepts.
That's the reason of my previous question.
Anyway I would like to understand how fluid molecules behave in pipes on a deeper level, at least as much as I can, given my poor background.
I drew this 2 pictures, hoping that they will help to illustrate what is a doubt that I currently have.
I imagined 2 vessels connected by a pipe.
The highest vessel is coninuosly alimented with new water. Water in excess flows down on the sides.
Water will try to reach the same height in both vessels, so some water will pour out of the shortest one and will be collected by the water collector.
The 2 figures are identical apart from the shape of the pipe distance d:
- In Picture 1 the pipe distance d starts with a restriction (from R1 to r2), then returns to the same diameter(R1) and then is restricted again(r2).
- In Picture 2 the pipe distance d is restricted (from R1 to r2) from the beginning to the end.
Given that we know all we need to know to calculate the pressure at point A, B and C ( Picture 1 ) and A' and C' ( Picture 2 ). I would like to know the difference in pressure between C and C', if there's any and why it's there. I'd love to hear an answer that explain everything in terms of water molecule's behaviour, if it's reasonable.
