Arteriosclerotic plaques forming on the inner walls of arteries can decrease the effective cross-sectional area of an artery. even small changes in the effective area of an artery can lead to very large changes in the blood pressure in the artery and possibly to the collapse of the blood vessel. imagine a healthy artery, with blood flow velocity of v0=0.14m/s and mass per unit volume of rho=1050kg/m3. the kinetic energy per unit volume of blood is given by

The kinetic energy per unit volume of blood is 10.29 .

Explanation:

The formula for the kinetic energy per unit volume (K) is given as follows:

--- (A)

Proof of the above formula: You must be wondering from where the aforementioned formula came, since the kinetic energy (KE) is .

Well, in this case, we need to find the Kinetic energy per unit volume (V).

Where,

K = Kinetic energy per unit volume = ?

= Density = Mass per unit volume =

v = velocity (which in this case is the flow velocity ) =

Plug the values in the equation (A):

Therefore, the kinetic energy per unit volume of blood is 10.29 .
