SUMMARY

The discussion clarifies why z1 equals z2 despite position 2 being higher than position 1, emphasizing that the scenario is viewed from a plan perspective. Participants confirm that the flow is maintained at a consistent horizontal level, indicating that the z-direction, which represents height, does not affect the equality of z1 and z2 in this context. The confusion arises from interpreting the diagram, which is indeed a top-down view rather than a side view.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with coordinate systems in physics
  • Knowledge of plan view versus side view representations
  • Basic grasp of flow continuity in fluid systems
NEXT STEPS
  • Study the principles of fluid dynamics, focusing on horizontal flow
  • Learn about coordinate systems and their applications in physics
  • Explore the differences between plan view and side view diagrams
  • Research flow continuity and its implications in fluid mechanics
USEFUL FOR

Students of physics, engineers working with fluid systems, and anyone seeking to understand the implications of coordinate representation in fluid dynamics.

The question is rather unclear, but I believe the diagram is the plan view, i.e. looking from above. (It doesn't say "45 degrees to the horizontal".)

the height of both are not the same, right??

No, I'm saying that the flow is all at the same horizontal level. Reread what I posted before.

if this is side view , the ther must be some value for z , right ? z can't be equal to 0 ?

but it isn't.

sorry , what do you mean ? i didnt get you

It's the plan view, i.e. you are looking down onto the pipe from above. The z direction is out of the page. The flow is all on one horizontal level.

if this is a side view , then z can't be = 0 , right ?

If it were a side view, that would be true.
