1. The problem statement, all variables and given/known data
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??

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 !
