Reynolds number will be 2416.3611

Explanation:

We have given diameter of aorta d = 2.15 cm = 0.0215m

Dynamic viscosity of blood $\mu =0.0027Pa-sec$

Fluid velocity $\v =28.9cm/sec=0.289m/sec$

Fluid density $\rho =1050kg/m^3$

We have to find the Reynolds number

We know that Reynolds number is given by

$R=\frac{\rho vd}{\mu }=\frac{1050\times 0.289\times 0.0215}{0.0027}=2416.3611$
