# Ever measured velocity of blood in an artery?

Using a Venturi meter, the flow of blood in a large artery of anesthetized dog is diverted. The wider part of that meter has a cross-sectional area equal to that of the artery and has magnitude $$8\text{ mm}^2$$. The narrower part has an area of $$4 \text{ mm}^2$$. The pressure drop in the artery is 24 pascals. What is the speed of the blood in the artery in $$\text{ms}^{-1}$$ ? Give your answer to correct three decimal places.

Take density of blood as $$1.06 \times 10^3 \text{ kg m}^{-3}$$.
