Question

Blood Flow. As blood moves through a vein or an artery, its velocity is greatest along the central axis and decreases as the distance from the central axis increases (see the figure).The formula that gives as a function of is called the law of laminar flow. For an artery with radius 0.5 cm, the relationship between and in cm is given by the function.

Find and

What do your answers to part (a) tell you about the flow of blood in this artery?

Make a table of values of for

Find the net change in the velocity as changes from 0.1cm to 0.5cm.
