Answer 1

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
Answer
It will decrease the flow rate by a factor of 0.5.
It will decrease the flow rate by a factor of 2.
It will increase the flow rate by a factor of 3.
It will increase the flow rate by a factor of 6.
