The blood speed in a normal segment of a horizontal artery is 0.140 m/s. an abnormal segment of the artery is narrowed down by an arteriosclerotic plaque to one-fourth the normal cross-sectional area. what is the difference in blood pressures between the normal and constricted segments of the artery?

Pa

Explanation:

Let "n" represents the normal flow condition and "a" represents the abnormal flow condition.

As per continuity equation -

----------- Eq (1)

Where "v" represents the velocity and "a" represents the area of artery

Given-

Substituting the above relation in equation (1), we get -

As per Bernoulli's theorem, we know that -
