Question

Calculate the Reynolds number for the blood flowing through an artery with a rate of flow of 6x10-6 m3/s with a radius of 4mm, and for an artery with the same rate of flow and a radius of 10% of the previous artery. The coefficient of viscosity for blood is about 2.7x10^-3 N s/m2. Would the flow of the second arterty be considered as laminar flow?
