What is the largest average velocity of blood flow in an artery of radius 2 × 10–3m if the flow must remain lanimar?


Reynolds’s number,


Where,


ρ = density of the fluid


v = largest average velocity of the fluid


D = diameter of the duct


μ = viscosity of the fluid


We have,


Density of the blood, ρ = 1.06 × 103 kg/m3


Reynolds’s number for laminar flow in duct, Re = 2000


Viscosity of the blood, μ = 2.084 × 10-3 Nm/s


Thus,


Largest average velocity,




= 0.982 m/s
