Q 10.25 In deriving Bernoulli’s equation, we equated the work done on the fluid in the tube to its change in the potential and kinetic energy.
(a) What is the largest average velocity of blood flow in an artery of diameter 2 × 10–3 m if the flow must remain laminar?
The diameter of the artery is
The viscosity of blood is
The density of blood is
The average velocity is given by
Taking the Maximum value of Reynold's Number ( NRe = 2000) at which Laminar Flow takes place we have
