Question

# Average speed of blood If the average volume flow of blood through the aorta is 8.50 × 10−5 m3/s and the cross-sectional area of the aorta is 3.00 × 10−4 m2, what is the average speed of blood in the aorta? cm/s

Answer

0.283 m/s

- Identify known values. A: The average volume flow of blood through the aorta is 8.50 × 10−5 m3/s and the cross-sectional area of the aorta is 3.00 × 10−4 m2.
- Use the formula v = Q/A to calculate the average speed of blood in the aorta, where v is the average speed, Q is the volume flow rate, and A is the cross-sectional area. A: v = (8.50 × 10^-5 m^3/s) / (3.00 × 10^-4 m^2) = 0.283 m/s.
