Which is True in an Expanded Aneurysm: 1-6?

AI Thread Summary
In an expanded aneurysm, the cross-sectional area of the vessel increases, affecting blood flow dynamics. The discussion centers on determining the correct relationship between flow, velocity, pressure, and density in this context. The assumption that blood is incompressible and non-viscous leads to the conclusion that as the area increases, the velocity of blood flow decreases, resulting in lower pressure in the expanded segment. The consensus leans towards option four, indicating that pressure is lower in the aneurysm compared to a normal vessel. Clarification on these principles is essential for understanding hemodynamics in vascular conditions.

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 !
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
