The speed of a fluid flowing inside a vessel is fastest at the center of the vessel and slowest at the wall of the vessel. the purpose of this problem is to demonstrate that the pattern of speeds fits closely to a parabola. this is the reason why cardiologists refer to it as "parabolic flow". to begin with, run the netlogo program channel 5-layer. following the procedure outlined in class, measure how long it takes for each of the 5 layers to move across the vessel. then, assuming the distance traveled across the vessel is 100 mm, calculate the speed of each layer in units of mm/tick.
