Question

A biology student wants to understand how blood flows through the aorta. To model the heart and aorta, she sets up two identical pressure-controlled tanks that push blood through a 2-centimeter diameter tube. Her results are shown in the table below. Using her findings, predict the outcome of the experiment if the pressure in a person's aorta were to triple, assuming her setup is an accurate model.





Blood Pressure

(in kilograms per square centimeter)


Flow Rate

(in milliliters per second)

Tank 1


1


20

Tank 2


0.5


10

A. It will decrease the flow rate by a factor of 0.5.
B. It will increase the flow rate by a factor of 3.
C. It will increase the flow rate by a factor of 6.
D. It will decrease the flow rate by a factor of 2.
