Question

What is the greatest average speed of blood flow at 37∘C in an artery of radius 2.25 mm if the flow is to remain laminar? Take the density of blood to be 1025 kg/m3,

and the viscosity to be 2.084×10^−3 Pa·s.

Answer 1

The greatest average speed of blood flow at 37°C in an artery of radius 2.25 mm if the flow is to remain laminar and the density of blood is 1025 kg/m³, would amount to 1.0165 m/s²

What is the greatest speed?

To calculate the average speed, we have the following details;

37°C

2.25 mm

1025 kg/m³

NR = 2pvr/n = 2250

v = 2250 * 2.084×10⁻³ / 2(1025 * 2.25 ×10⁻³)

v= 2334.5156/2296.43

v = 1.0165 m/s²

So the greatest average speed of blood flow at 37°C in an artery of radius 2.25 mm if the flow is to remain laminar and the density of blood is 1025 kg/m³, is 1.0165 m/s².
