    . Now decrease the right flow tube radius to 2.5 mm, and run another trial. How does this flow rate compare with “normal”? Leave the right flow tube radius at 2.5 mm radius and try to adjust one or more other conditions to return flow to “normal.” Think logically about what condition(s) might...

    , increase left baker pressure and decrease right beaker pressure. 22. A decreased tube radius is analogous to atherosclerosis (plaque formation in vessels). Describe the effect this would have on resistance in the arterial system and how the human heart might compensate for this change. Atherosclerosis causes an increased atrial resistance which causes the heart to compensate by increasing pumping pressure....
