15. Capacity

17. over under
capacity capacity

18. under
capacity
◦For a while increasing
the density increases
the flow.
◦Increasing the flow
causes the density to
reduce.
◦ Thus you have a
stabilizing feedback loop
helping to increase the
flow.

19. ◦As you continue to
increase the density
you reach the top of the
flow-curve.

20. over
capacity
◦As the density
increases the flow
decreases.
◦Decreasing the flow
causes the density to
further increase.
◦Thus you have a
different destabilizing
feedback loop helping
to decrease the flow.
