Homework Help Overview

The discussion revolves around the equality of two variables, z1 and z2, in the context of a problem involving positions and heights. Participants are trying to understand why z1 equals z2 despite one position being higher than the other, with a focus on the interpretation of a diagram that may depict a plan view versus a side view.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants express confusion about the clarity of the question and the implications of the diagram's perspective. There are attempts to clarify whether the view is from above or the side, and questions about the implications of height differences on the values of z1 and z2.

Discussion Status

The discussion is ongoing, with participants providing insights into the interpretation of the diagram and questioning the assumptions about the flow and height levels. Some guidance has been offered regarding the perspective of the view, but no consensus has been reached on the implications for z1 and z2.

Contextual Notes

There is uncertainty regarding the diagram's orientation and whether it is a plan view or a side view, which affects the understanding of the variables in question. Participants are also considering the implications of horizontal flow on the values of z.

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.
