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  

=>

like poles repel so keep pushing north to north and repels funny to see this

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
