Instead of running blood through a single straight vessel for a distance of 2 mm, one mammalian species uses an array of 100 tiny parallel pipes of the same total cross-sectional area, 4.0 mm2. Volume flow is 1000 mm3/s. The pressure drop for fluid passing through the single pipe is lower than that through the 100 vessel array by a factor of:. A. 10
B. 100
C. 1000

Solution:

Given that :

Volume flow is,

So,

Therefore, the equation of a single straight vessel is given by

   ......................(i)

So there are 100 similar parallel pipes of the same cross section. Therefore, the equation for the area is

or

Now for parallel pipes

 ...........(ii)

Solving the equations (i) and (ii),

Therefore,

or

Thus the answer is option A). 10
