The largest artery in the body is the aorta. if the maximum diameter of the aorta is 2 cm, and the maximum average velocity of the blood is 20 cm/s, determine if the flow in the aorta is laminar or turbulent (assume that blood has the same density as water but three times its viscosityblood, after all, is thicker than water).
