Answer to Question #268493 in Physics for Steph

Question

Given a starting resistance of 4g/cm4s and volumetric flow rate of 10 mL/s, what is the final resistance if the artery vasodilates 2x its original size? What is the final volumetric flow rate?

Given a starting resistance of 1g/cm4s, and volumetric flow rate of 9 mL/s, what is the final resistance if the radius of the artery gets 3x smaller? What is the final volumetric flow rate?

During stenosis, plaque builds up an artery. The original volumetric flow rate is 30 mL/s, the normal speed of blood in the vessel is 100cm/s and the original cross sectional area is 2 cm2. If we are dealing with 50% stenosis. what speed would we measure within the artery? What volumetric flow rate would we measure?
