Problem Solving: Read and analyze the following problems then write your complete solution and emphasize your final answer. 1. Poiseuille's law remains valid as long as the fluid flow is laminar. For sufficiently high speed, however, the flow becomes turbulent, even if the fluid is moving through a smooth pipe with no restrictions. It is found experimentally that the flow is laminar as long as the Reynolds number Nre is less than about 2000: Re= 2vpR/n. Here, v, and pn are respectively, the average speed, density, and viscosity of the fluid, and R is the radius of the pipe. Calculate the highest average speed that blood (p=1060 kg/m³, n = 4.0 x10-3 Pa s) could have and still remain in laminar flow when it flows through the aorta (R = 8.0 x103 m). %3D
