Answer to Question #122382 in Mechanical Engineering for Aakash

Question

Consider arterial blood viscosity µ = .0 025 poise. If the length of the artery is 1.5cm, radius 8*10^(-3) cm
P = P− P = 4×10^3dynes/cm^2 then find (i) maximum peak velocity of
blood and (ii) the shear stress at the wall.

Answer 1

Assuming laminar flow of blood through the artery.

The maximum velocity is given by

The wall shear stress is given by
