Homework Help Overview

The discussion revolves around the behavior of blood flow in an expanded aneurysm, specifically examining the relationships between flow, velocity, pressure, and density under the assumptions of non-viscous and incompressible fluid dynamics with laminar flow.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are considering the implications of the assumptions made about blood flow, particularly questioning which statements about flow, velocity, and pressure are true in the context of an aneurysm.

Discussion Status

Some participants have offered insights into the assumptions, such as the incompressibility of blood, while others are expressing uncertainty and seeking clarification on the correct answer among the provided options. There is an ongoing exploration of the relationships between the variables involved.

Contextual Notes

The original poster mentions having limited attempts to answer the question, which may influence the urgency and nature of the discussion.

Homework Statement


In an aneurysm, the cross-sectional area of a vessel expands. With the approximation that blood is non-viscous and incompressible, and that you have laminar flow, which one of the following is true in the expanded segment, compared to the normal vessel?
1.The flow is higher
2.The velocity is higher
3.The velocity is the same
4.The pressure is lower
5.The density of the blood increases
6.None of the above

I have just two tries for this question! Can you help please?? :confused:

What do you think? I'll tell you that it can't be 5 because the blood is assumed to be incompressible.
 


I think its the fourth answer, since I is higher, then the pressure is lower !
 


Is there any answer? I need help with this !
