Question

Blood is pumped from the heart at a rate of 9 L/min into the aorta (of radius 6.62 cm). Determine the speed of blood through the aorta.

Round your answer to 3 decimal places

Answer 1

Answer

Flow rateQ is defined as

$Q=\frac{V}{t}=Av$

where V is the volume and t is the elapsed time.

So velocity is given by

$v=\frac{Q}{A}\\=\frac{9\times10^{-3}}{60\times3.14\times6.62\times6.62\times10^{-4}}$

$=0.0109m/s$
