Releasing adrenaline dilates blood vessels, making it easier for blood to flow. By about what percentage would the diameter of a blood vessel need to increase to raise blood flow by 20%, at constant Blood pressure?
1.) 0%
b.) 4.7%
c.) 10%
d.) 20%
I originally tried to solve this problem using
Q=vr^2
Because nearly all of the previous passages treated blood as an ideal fluid.
But they want us to treat blood as a non-ideal fluid here and use Q=r^4 relationship.
I'm wondering why we assume that blood here is a non-ideal fluid? Is that just a general rule to assume Everything is non-ideal viscous unless we are told otherwise?
