its diameter by 22%, but the volume flow rate of blood in the artery remains the

across the length of this artery increased?

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 the pressure drop across the length of this artery increased?
(1/0.78)^4=2.7
