An abdominal aortic aneurysm has cross-sectional area 2 cm^2 and a blood flow velocity of 20 cm/s. What is the flow rate in L/min through the aneurysm?

Explanation:
Flow rate equals cross-sectional area times velocity. Multiply the area by the velocity: 2 cm^2 × 20 cm/s = 40 cm^3/s. Since 1 cm^3 is 1 mL, that’s 40 mL/s. Convert to liters per minute: 40 mL/s is 0.04 L/s, and 0.04 L/s × 60 s/min = 2.4 L/min. So the flow rate is 2.4 L/min.
