The blood speed in a normal segment of a horizontal artery is 0.16 m/s. An abnormal segment of the artery is narrowed down by an arteriosclerotic plaque to one-eighth the normal cross-sectional area. What is the difference in blood pressures between the normal and constricted segments of the artery?

The difference in blood  pressures is

Explanation:

From the question we are told that

  The blood speed in a normal segment is  

   The area  of the normal segment is  

   The area of the abnormal segment is  

Generally from continuity equation we have that

=>    

=>    

=>    

Generally from Bernoulli's equation the difference in pressure is mathematically represented as

Here   is the density of blood with value  

=>

i think its

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
