Problem 72P
· BIO An Occlusion in an Artery Suppose an occlusion in an artery reduces its diameter by 15%, but the volume flow rate of blood in the artery remains the same. By what factor has th pressure drop across the length of this artery increased?
ANSWER:
Step 1 of 3
We have to find by what factor does the pressure drop across the length of the artery increases if an occlusion reduces its diameter by 15 %.
The pressure drop across the length of the artery can be found using Poiseuille's equation.
where,
volume flow rate
= pressure drop across the length of the artery
= radius of the artery
viscosity of blood
length of the artery
