Suppose that there is a partial blockage of the aorta, which normally pumps about 5 L of blood per minute. If the diameter of the aorta is reduced by 30%, find the average flow rate through the diseased aorta. What increase in blood pressure would be needed to obtain the normal flow rate? (Assume that Poiscuille's law applies.)

Explanation:

a. The pressure gradient would have to increase by a factor of 3.33.3.

b. The pressure gradient would have to increase by a factor of 1.41.4.

c. The pressure gradient would have to increase by a factor of 4.24.2.

d. The pressure gradient would have to increase by a factor of 123123.

e. The pressure gradient would have to increase by a factor of 22.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
