The flow rate of blood through the average human aorta,of radius 1.0 cm,is about 90 cm³/s.What is the speed of the blood flow through the aorta? A) 14 cm/s B) 32 cm/s C) 37 cm/s D) 29 cm/s

Question

The speed of blood flow can be calculated using the formula: speed = flow rate / cross-sectional area. The cross-sectional area of the aorta is πr², where r = 1.0 cm. Thus, the area is π(1.0)² = π cm². The speed is then 90 cm³/s ÷ π cm² ≈ 28.65 cm/s, which rounds to 29 cm/s.
