Blood flow + blockage?!?

Using the hagen-poiseuille equation fror expected blood flow, how would a blockage of halving the cross sectional area of the vessel effect the expected flow rate?

Q = (/_\P x pi x r^4) / (8 x viscosity x length of vessel)

is it as simple as halving the radius?

Answers:
1/16

you are having the diameter, so the radius is always being halve, and as you can see, r is raised to the power of 4. (1/2)^4 = 1/16 Source(s): Med student
